Why Does Ketoacidosis Cause Vomiting

Understanding The Presentation Of Diabetic Ketoacidosis

Understanding The Presentation Of Diabetic Ketoacidosis

Hypoglycemia, diabetic ketoacidosis (DKA) and hyperglycemic hyperosmolar nonketotic syndrome (HHNS) must be considered while forming a differential diagnosis when assessing and managing a patient with an altered mental status. This is especially true if the patient has a history of diabetes mellitus (DM). However, be aware that the onset of DKA or HHNS may be the first sign of DM in a patient with no known history. Thus, it is imperative to obtain a blood glucose reading on any patient with an altered mental status, especially if the patient appears to be dehydrated, regardless of a positive or negative history of DM. In addition to the blood glucose reading, the history — particularly onset — and physical assessment findings will contribute to the formulation of a differential diagnosis and the appropriate emergency management of the patient. Pathophysiology of DKA The patient experiencing DKA presents significantly different from one who is hypoglycemic. This is due to the variation in the pathology of the condition. Like hypoglycemia, by understanding the basic pathophysiology of DKA, there is no need to memorize signs and symptoms in order to recognize and differentiate between hypoglycemia and DKA. Unlike hypoglycemia, where the insulin level is in excess and the blood glucose level is extremely low, DKA is associated with a relative or absolute insulin deficiency and a severely elevated blood glucose level, typically greater than 300 mg/dL. Due to the lack of insulin, tissue such as muscle, fat and the liver are unable to take up glucose. Even though the blood has an extremely elevated amount of circulating glucose, the cells are basically starving. Because the blood brain barrier does not require insulin for glucose to diffuse across, the brain cells are rece Continue reading >>

Diabetic Ketoacidosis

Diabetic Ketoacidosis

Diabetic acidosis is a life-threatening condition that can occur in people with type 1 diabetes. Less commonly, it can also occur with type 2 diabetes. Term watch Ketones: breakdown products from the use of fat stores for energy. Ketoacidosis: another name for diabetic acidosis. It happens when a lack of insulin leads to: Diabetic acidosis requires immediate hospitalisation for urgent treatment with fluids and intravenous insulin. It can usually be avoided through proper treatment of Type 1 diabetes. However, ketoacidosis can also occur with well-controlled diabetes if you get a severe infection or other serious illness, such as a heart attack or stroke, which can cause vomiting and resistance to the normal dose of injected insulin. What causes diabetic acidosis? The condition is caused by a lack of insulin, most commonly when doses are missed. While insulin's main function is to lower the blood sugar level, it also reduces the burning of body fat. If the insulin level drops significantly, the body will start burning fat uncontrollably while blood sugar levels rise. Glucose will then begin to show up in your urine, along with ketone bodies from fat breakdown that turn the body acidic. The body attempts to reduce the level of acid by increasing the rate and depth of breathing. This blows off carbon dioxide in the breath, which tends to correct the acidosis temporarily (known as acidotic breathing). At the same time, the high secretion of glucose into the urine causes large quantities of water and salts to be lost, putting the body at serious risk of dehydration. Eventually, over-breathing becomes inadequate to control the acidosis. What are the symptoms? Since diabetic acidosis is most often linked with high blood sugar levels, symptoms are the same as those for diabetes Continue reading >>

Acute Complications Of Diabetes - Diabetic Ketoacidosis

Acute Complications Of Diabetes - Diabetic Ketoacidosis

- [Voiceover] Oftentimes we think of diabetes mellitus as a chronic disease that causes serious complications over a long period of time if it's not treated properly. However, the acute complications of diabetes mellitus are often the most serious, and can be potentially even life threatening. Let's discuss one of the acute complications of diabetes, known as diabetic ketoacidosis, or DKA for short, which can occur in individuals with type 1 diabetes. Now recall that type 1 diabetes is an autoimmune disorder. And as such, there's an autoimmune destruction of the beta cells in the pancreas, which prevents the pancreas from producing and secreting insulin. Therefore, there is an absolute insulin deficiency in type 1 diabetes. But what exactly does this mean for the body? To get a better understanding, let's think about insulin requirements as a balancing act with energy needs. Now the goal here is to keep the balance in balance. As the energy requirements of the body go up, insulin is needed to take the glucose out of the blood and store it throughout the body. Normally in individuals without type 1 diabetes, the pancreas is able to produce enough insulin to keep up with any amount of energy requirement. But how does this change is someone has type 1 diabetes? Well since their pancreas cannot produces as much insulin, they have an absolute insulin deficiency. Now for day-to-day activities, this may not actually cause any problems, because the small amount of insulin that is produced is able to compensate and keep the balance in balance. However, over time, as type 1 diabetes worsens, and less insulin is able to be produced, then the balance becomes slightly unequal. And this results in the sub-acute or mild symptoms of type 1 diabetes such as fatigue, because the body isn Continue reading >>

Is Diabetes Causing My Nausea?

Is Diabetes Causing My Nausea?

Nausea comes in many forms. Sometimes it can be mild and short-lived. Other times, it can be severe and last for a long time. For people with diabetes, nausea is a common complaint. It can even be a sign of a life-threatening condition that requires swift medical attention. 5 common causes of nausea Factors related to your diabetes may cause you to feel nausea. Medication Metformin (Glucophage) is one of the more common medications used to treat diabetes. Nausea is a potential side effect for people taking this medication. Taking metformin on an empty stomach may make nausea worse. Injectable medications used to treat diabetes, such as exenatide (Byetta), liraglutide (Victoza), and pramlintide (Symlin), may also cause nausea. The nausea may go away after extended use. Your doctor may also start you on a lower dosage to try to reduce or eliminate nausea. Hypo- and hyperglycemia Hyperglycemia (elevated blood sugar levels) or hypoglycemia (blood sugar levels that are too low) may cause nausea. Check your blood sugar and respond appropriately if you suspect abnormal blood sugar levels. To avoid hypo- and hyperglycemia, stick to your diabetes meal plan, monitor your blood sugar, and take your medication as prescribed. You should also avoid exercising in extreme temperatures and keep cool by drinking cold liquids during outside activities, advises Sheri Colberg, PhD, author, exercise physiologist, and expert on diabetes management. Diabetic ketoacidosis Severe nausea may be a sign of diabetic ketoacidosis. This is a dangerous medical condition that must be treated to avoid coma or even death. Symptoms include: nausea excessive thirst frequent urination abdominal pain weakness or fatigue shortness of breath confusion fruity-scented breath If you suspect diabetic ketoacidosis, Continue reading >>

Vomiting, Nausea, And Diarrhea – Adjusting Your Diabetes Medication

Vomiting, Nausea, And Diarrhea – Adjusting Your Diabetes Medication

Vomiting, nausea, and diarrhea are most commonly caused by bacterial or viral infections sometimes associated with flu-like illness. An essential part of treatment is to stop eating. Since you can certainly survive a few days without eating, this should pose no problem. But if you’re not eating, it makes sense to ask what dose of insulin or ISA you should take. Adjusting Your Diabetes Medication If you’re on one of the medication regimens described in this book, the answer is simple: you take the amount and type of medication that you’d normally take to cover the basal, or fasting, state and skip any doses that are intended to cover meals. If, for example, you ordinarily take detemir or glargine as basal insulin upon arising and at bedtime, and regular or lispro (or aspart or glulisine) insulin before meals, you’d continue the basal insulin and skip the preprandial regular or lispro for those meals you won’t be eating. Similarly, if you take an ISA on arising and/or at bedtime for the fasting state, and again to cover meals, you skip the doses for those meals that you do not plan to eat. In both of the above cases, it’s essential that the medications used for the fasting state continue at their full doses. This is in direct contradiction to traditional “sick day” treatment, but it’s a major reason why patients who carefully follow our regimens should not develop DKA or hyperosmolar coma when they are ill. Of course, if you’re vomiting, you won’t be able to keep down oral medication and this poses yet another problem. Remember, because infection and dehydration may each cause blood sugar to increase, you may need additional coverage for any blood sugar elevation. Such additional coverage should usually take the form of lispro insulin. This is one of Continue reading >>

The Emedicinehealth Doctors Ask About Diabetic Ketoacidosis:

A A A Diabetic Ketoacidosis (cont.) A person developing diabetic ketoacidosis may have one or more of these symptoms: excessive thirst or drinking lots of fluid, frequent urination, general weakness, vomiting, loss of appetite, confusion, abdominal pain, shortness of breath, a generally ill appearance, increased heart rate, low blood pressure, increased rate of breathing, and a distinctive fruity odor on the breath. If you have any form of diabetes, contact your doctor when you have very high blood sugars (generally more than 350 mg) or moderate elevations that do not respond to home treatment. At initial diagnosis your doctor should have provided you with specific rules for dosing your medication(s) and for checking your urinary ketone level whenever you become ill. If not, ask your health care practitioner to provide such "sick day rules." If you have diabetes and start vomiting, seek immediate medical attention. If you have diabetes and develop a fever, contact your health care practitioner. If you feel sick, check your urinary ketone levels with home test strips. If your urinary ketones are moderate or higher, contact your health care practitioner. People with diabetes should be taken to a hospital's emergency department if they appear significantly ill, dehydrated, confused, or very weak. Other reasons to seek immediate medical treatment include shortness of breath, chest pain, severe abdominal pain with vomiting, or high fever (above 101 F or 38.3 C).

Physiology Of Vomiting

Physiology Of Vomiting

"At least after death you're not nauseous." Woody Allen in Sleeper Vomiting is the forceful expulsion of contents of the stomach and often, the proximal small intestine. It is a manifestation of a large number of conditions, many of which are not primary disorders of the gastrointestinal tract. Regardless of cause, vomiting can have serious consequences, including acid-base derangments, volume and electrolyte depletion, malnutrition and aspiration pneumonia. The Act of Vomiting Vomiting is usually experienced as the finale in a series of three events, which everyone reading this has experienced: Nausea is an unpleasant and difficult to describe psychic experience in humans and probably animals. Physiologically, nausea is typically associated with decreased gastric motility and increased tone in the small intestine. Additionally, there is often reverse peristalsis in the proximal small intestine. Retching ("dry heaves") refers to spasmodic respiratory movements conducted with a closed glottis. While this is occurring, the antrum of the stomach contracts and the fundus and cardia relax. Studies with cats have shown that during retching there is repeated herniation of the abdominal esophagus and cardia into the thoracic cavity due to the negative pressure engendered by inspiratory efforts with a closed glottis. Emesis or vomition is when gastric and often small intestinal contents are propelled up to and out of the mouth. It results from a highly coordinated series of events that could be described as the following series of steps (don't practice these in public): A deep breath is taken, the glottis is closed and the larynx is raised to open the upper esophageal sphincter. Also, the soft palate is elevated to close off the posterior nares. The diaphragm is contracted sharp Continue reading >>

Symptoms

Symptoms

The symptoms of type 1 diabetes can develop very quickly (over a few days or weeks), particularly in children. In older adults, the symptoms can often take longer to develop (a few months). However, they should disappear when you start taking insulin and the condition is under control. The main symptoms of diabetes are: feeling very thirsty urinating more frequently than usual, particularly at night feeling very tired weight loss and loss of muscle bulk itchiness around the genital area, or regular bouts of thrush (a yeast infection) blurred vision caused by the lens of your eye changing shape slow healing of cuts and grazes Vomiting or heavy, deep breathing can also occur at a later stage. This is a dangerous sign and requires immediate admission to hospital for treatment. See your GP if you think you may have diabetes. When to seek urgent medical attention You should seek urgent medical attention if you have diabetes and develop: a loss of appetite nausea or vomiting a high temperature stomach pain fruity smelling breath – which may smell like pear drops or nail varnish (others will usually be able to smell it, but you won't) Hypoglycaemia (low blood glucose) If you have diabetes, your blood glucose levels can become very low. This is known as hypoglycaemia (or a "hypo"), and it's triggered when injected insulin in your body moves too much glucose out of your bloodstream. In most cases, hypoglycaemia occurs as a result of taking too much insulin, although it can also develop if you skip a meal, exercise very vigorously or drink alcohol on an empty stomach. Symptoms of a "hypo" include: feeling shaky and irritable sweating tingling lips feeling weak feeling confused hunger nausea (feeling sick) A hypo can be brought under control simply by eating or drinking somethin Continue reading >>

Nausea And Vomiting

Nausea And Vomiting

Tweet Most, if not all of us will be familiar with the feeling of nausea, which is basically the feeling of needing to be sick, felt in the stomach area. Both nausea and vomiting can be a sign of a number of underlying health conditions, including diabetes. When there is an issue that can affect the stomach or gastric system of their body, people can feel sick. Even if it is a fairly tenuous connection, such as angina affecting blood flow, the sufferer may still feel queasy. Causes of nausea Both type 1 diabetes and type 2 diabetes can cause nausea or vomiting in several ways. Hyperglycemia and Hypoglycemia As the blood glucose levels rise and fall, the body's metabolism can get interrupted and confused which can lead to a mixed feeling of nausea. Low blood pressure (Hypotension) Low blood pressure often leads to dizzy spells which, for some people, can induce a feeling of nausea as the world appears to spin around them. Certain medications The side effect of a lot of drugs is a feeling of nausea, and even vomiting. Metformin, the most widely used diabetes drug, is known to have nauseating side effects. Gastroparesis Due to neuropathy, the body may not be able to move food from the stomach or along the intestines. This can cause a back log of food, which can result in sickness. Bezoars Bezoars are stone like formations created from undigested food matter, which can block the gastro-intestinal track and stop food processing and digesting. This can eventually cause nausea and vomiting. When to see your doctor If you are having recurrent or consistent bouts of nausea or vomiting, then it is a good idea to go and see your doctor to get the issue sorted as soon as possible. Keeping a diary of nausea or vomiting episodes and what you ate or were doing beforehand may help the Continue reading >>

Diabetic Ketoacidosis

Diabetic Ketoacidosis

What Is It? Diabetic ketoacidosis is a potentially fatal complication of diabetes that occurs when you have much less insulin than your body needs. This problem causes the blood to become acidic and the body to become dangerously dehydrated. Diabetic ketoacidosis can occur when diabetes is not treated adequately, or it can occur during times of serious sickness. To understand this illness, you need to understand the way your body powers itself with sugar and other fuels. Foods we eat are broken down by the body, and much of what we eat becomes glucose (a type of sugar), which enters the bloodstream. Insulin helps glucose to pass from the bloodstream into body cells, where it is used for energy. Insulin normally is made by the pancreas, but people with type 1 diabetes (insulin-dependent diabetes) don't produce enough insulin and must inject it daily. Your body needs a constant source of energy. When you have plenty of insulin, your body cells can get all the energy they need from glucose. If you don't have enough insulin in your blood, your liver is programmed to manufacture emergency fuels. These fuels, made from fat, are called ketones (or keto acids). In a pinch, ketones can give you energy. However, if your body stays dependent on ketones for energy for too long, you soon will become ill. Ketones are acidic chemicals that are toxic at high concentrations. In diabetic ketoacidosis, ketones build up in the blood, seriously altering the normal chemistry of the blood and interfering with the function of multiple organs. They make the blood acidic, which causes vomiting and abdominal pain. If the acid level of the blood becomes extreme, ketoacidosis can cause falling blood pressure, coma and death. Ketoacidosis is always accompanied by dehydration, which is caused by high Continue reading >>

Diabetic Ketoacidosis

Diabetic Ketoacidosis

Introduction Diabetic ketoacidosis (DKA) is a dangerous complication of diabetes caused by a lack of insulin in the body. Diabetic ketoacidosis occurs when the body is unable to use blood sugar (glucose) because there isn't enough insulin. Instead, it breaks down fat as an alternative source of fuel. This causes a build-up of a by-product called ketones. Most cases of diabetic ketoacidosis occur in people with type 1 diabetes, although it can also be a complication of type 2 diabetes. Symptoms of diabetic ketoacidosis include: passing large amounts of urine feeling very thirsty vomiting abdominal pain Seek immediate medical assistance if you have any of these symptoms and your blood sugar levels are high. Read more about the symptoms of diabetic ketoacidosis. Who is affected by diabetic ketoacidosis? Diabetic ketoacidosis is a relatively common complication in people with diabetes, particularly children and younger adults who have type 1 diabetes. Younger children under four years of age are thought to be most at risk. In about 1 in 4 cases, diabetic ketoacidosis develops in people who were previously unaware they had type 1 diabetes. Diabetic ketoacidosis accounts for around half of all diabetes-related hospital admissions in people with type 1 diabetes. Diabetic ketoacidosis triggers These include: infections and other illnesses not keeping up with recommended insulin injections Read more about potential causes of diabetic ketoacidosis. Diagnosing diabetic ketoacidosis This is a relatively straightforward process. Blood tests can be used to check your glucose levels and any chemical imbalances, such as low levels of potassium. Urine tests can be used to estimate the number of ketones in your body. Blood and urine tests can also be used to check for an underlying infec Continue reading >>

> Hyperglycemia And Diabetic Ketoacidosis

> Hyperglycemia And Diabetic Ketoacidosis

When blood glucose levels (also called blood sugar levels) are too high, it's called hyperglycemia. Glucose is a sugar that comes from foods, and is formed and stored inside the body. It's the main source of energy for the body's cells and is carried to each through the bloodstream. But even though we need glucose for energy, too much glucose in the blood can be unhealthy. Hyperglycemia is the hallmark of diabetes — it happens when the body either can't make insulin (type 1 diabetes) or can't respond to insulin properly (type 2 diabetes). The body needs insulin so glucose in the blood can enter the cells to be used for energy. In people who have developed diabetes, glucose builds up in the blood, resulting in hyperglycemia. If it's not treated, hyperglycemia can cause serious health problems. Too much sugar in the bloodstream for long periods of time can damage the vessels that supply blood to vital organs. And, too much sugar in the bloodstream can cause other types of damage to body tissues, which can increase the risk of heart disease and stroke, kidney disease, vision problems, and nerve problems in people with diabetes. These problems don't usually show up in kids or teens with diabetes who have had the disease for only a few years. However, they can happen in adulthood in some people, particularly if they haven't managed or controlled their diabetes properly. Blood sugar levels are considered high when they're above someone's target range. The diabetes health care team will let you know what your child's target blood sugar levels are, which will vary based on factors like your child's age. A major goal in controlling diabetes is to keep blood sugar levels as close to the desired range as possible. It's a three-way balancing act of: diabetes medicines (such as in Continue reading >>

Symptoms And Detection Of Ketoacidosis

Symptoms And Detection Of Ketoacidosis

Symptoms These symptoms are due to the ketone poisoning and should never be ignored. As soon as a person begins to vomit or has difficulty breathing, immediate treatment in an emergency room is required to prevent coma and possible death. Early Signs, Symptoms: Late Signs, Symptoms: very tired and sleepy weakness great thirst frequent urination dry skin and tongue leg cramps fruity odor to the breath* upset stomach* nausea* vomiting* shortness of breath sunken eyeballs very high blood sugars rapid pulse rapid breathing low blood pressure unresponsiveness, coma * these are more specific for ketoacidosis than hyperosmolar syndrome Everyone with diabetes needs to know how to recognize and treat ketoacidosis. Ketones travel from the blood into the urine and can be detected in the urine with ketone test strips available at any pharmacy. Ketone strips should always be kept on hand, but stored in a dry area and replaced as soon as they become outdated. Measurement of Ketones in the urine is very important for diabetics with infections or on insulin pump therapy due to the fact it gives more information than glucose tests alone. Check the urine for ketones whenever a blood sugar reading is 300 mg/dl or higher, if a fruity odor is detected in the breath, if abdominal pain is present, if nausea or vomiting is occurring, or if you are breathing rapidly and short of breath. If a moderate or large amount of ketones are detected on the test strip, ketoacidosis is present and immediate treatment is required. Symptoms for hyperglycemic hyperosmolar syndrome are linked to dehydration rather than acidosis, so a fruity odor to the breath and stomach upset are less likely. How To Detect Ketones During any illness, especially when it is severe and any time the stomach becomes upset, ketone Continue reading >>

Ketoacidosis: A Diabetes Complication

Ketoacidosis: A Diabetes Complication

Ketoacidosis can affect both type 1 diabetes and type 2 diabetes patients. It's a possible short-term complication of diabetes, one caused by hyperglycemia—and one that can be avoided. Diabetic ketoacidosis (DKA) and hyperosmolar hyperglycemic state (HHS) are two of the most serious complications of diabetes. These hyperglycemic emergencies continue to be important causes of mortality among persons with diabetes in spite of all of the advances in understanding diabetes. The annual incidence rate of DKA estimated from population-based studies ranges from 4.8 to 8 episodes per 1,000 patients with diabetes. Unfortunately, in the US, incidents of hospitalization due to DKA have increased. Currently, 4% to 9% of all hospital discharge summaries among patients with diabetes include DKA. The incidence of HHS is more difficult to determine because of lack of population studies but it is still high at around 15%. The prognosis of both conditions is substantially worsened at the extremes of age, and in the presence of coma and hypertension. Why and How Does Ketoacidosis Occur? The pathogenesis of DKA is more understood than HHS but both relate to the basic underlying reduction in the net effective action of circulating insulin coupled with a concomitant elevation of counter regulatory hormones such as glucagons, catecholamines, cortisol, and growth hormone. These hormonal alterations in both DKA and HHS lead to increased hepatic and renal glucose production and impaired use of glucose in peripheral tissues, which results in hyperglycemia and parallel changes in osmolality in extracellular space. This same combination also leads to release of free fatty acids into the circulation from adipose tissue and to unrestrained hepatic fatty acid oxidation to ketone bodies. Some drugs ca Continue reading >>

Gastroparesis: A Complication Of Diabetes

Gastroparesis: A Complication Of Diabetes

"Gastro" means stomach and "paresis" means impairment or paralysis. Diabetic gastropathy is a term for the spectrum of neuromuscular abnormalities of the stomach caused by diabetes. The abnormalities include gastric-dysrhythmias, antral hypomotility, incoordination of antroduodenal contractions and gastroparesis. Quick Stomach Anatomy Lesson The stomach is a neuromusclar organ that receives the food we ingest, mixes the food with acid and pepsin, and empties the nutriment suspension into the small intestine for absorption. The proximal stomach or fundus relaxes in order to receive the swallowed food (that's called receptive relaxation). The body and antrum mix and empty the food via recurrent gastric peristalic waves. The peristaltic contractions are paced by neoelectrical events called pacesetter potentials or slow waves. When gastric motility is normal, the postprandial (after eating) period is associated with pleasant epigastric sensations. Gastric motility disorders or gastroparesis presents with unpleasant, but non-specific postprandial symptoms: upper abdominal bloating, distention, discomfort, early satiety, nausea, and vomiting. If the vomitus contains undigested food, then gastroparesis is very likely to be present. Fluctuating, difficult-to-predict glucose levels may also reflect the presence of gastroparesis. Diabetes and the GI Tract The motility of your GI tract, which we were just speaking of, is controlled by an outer sleeve of muscles that surrounds your GI tract. They are controlled by a complex nervous system. Diabetes can damage these nerves, and it is this neurological long-term complication of diabetes that can lead to gastrointestinal disorders. How do we know this is the case? First, many of the people with gastroparesis have long-standing diabete Continue reading >>
