Diabetic Seizures In Dogs

Seeing your dog have a seizure can be pretty scary, especially the first time this happens. If the seizure is caused by diabetes complications, the good news is that future seizures can be prevented by controlling the dog's diabetes. Why Seizures Happen Any seizure—in a dog or a human—is caused by a kind of electrical storm in the brain. If a dog has diabetes, her body doesn't produce the right amount of insulin for control of blood sugar levels. Insulin is produced by the pancreas, and diabetes can be caused by too much or too little. Very low blood sugar levels can interrupt the normal functioning of the brain, leading to a diabetic seizure. Hypoglycemia and Hyperglycemia Problems relating to diabetes in dogs usually stem from a state of either hypoglycemia or hyperglycemia. A hypoglycemic dog has very low blood sugar and may experience a seizure as a result. In diabetic dogs, hypoglycemia commonly occurs when an insulin dose is given without sufficient food for the dog's body to utilize the insulin properly. The opposite diabetic state, hyperglycemia, occurs when the dog's blood sugar levels are extremely high. Although hyperglycemia does not typically cause seizures, this i Continue reading >>

    My cat is 16 and diagnosed with diabetes about 2 years ago. I changed the food and he went into remission once. Then it came back along with thyroid problems. I test with a meter before I give him insulin. He was in the high 200 and 300 range about 4 months ago and we were doing 3 units of vetsulin. Then he would be around 100 - 150 early in the day and 200-300 or so in the evening, so I would give him the 3 units only when he was high. Saturday and Sunday, when I tested him with the meter, he didn't need a shot at all. Last night, I tested him and he was 218. I gave him 3 units. I think this was a big mistake since he has been getting lower, he was probably already going into remission or at least staying below 200, so after giving him the insulin, his own body probably went lower and then the insulin made him plummet. I went to bed at 3 AM and got up at 11:30 (I was laid off and I stay up late looking for jobs). He was walking around the house against the walls and furniture acting very strangely sniffing everything. I didn't get it for awhile. I thought it was because we have this other cat he hasn't been getting along with and has been spraying stuff and I thought that is what he was sniffing. I checked his blood sugar and it was 33! Gave him Karo and it went to 42. Took him to the vet and he said his retinas are working and he is just disoriented. He ate lots of food while there and his blood sugar went to 160 so I brought him home. That was around 3 PM. Its almost 6 hours later and he is still walking around the house against the walls and furniture sniffing and getting in strange positions and acting like he can't see. I don't know if this has permanently caused blindness or semi blindness or if he will get better. I checked him again and he is at 202. I am definitely not going to give him any insulin. I think he was starting to go back into remission and I should not have given him that shot at 3 AM. Who knows how low his BS went - it could have been well below 33 while I was sleeping. I should have not given him any or just one unit.

    I'm cross posting on the other boards for you. Hang on.

    yes, a severe hypo event can cause blindness. often it is not permanent though. it can take some time for all the senses to come back and be fully functioning again so for now, be patient with him and make sure he cannot hurt himself. you may need to confine him to one room for now so he doesn't hurt himself.
    in the meantime, yes, dont' give any insulin at this point. let his body sort things out some and in a day or so, see what his levels are and then if he's high enough, start over at a much lower dose. 3 units is usually too high of a dose so let's work on reading and asking questions and learning some more about your insulin and this disease before we reintroduce him to insulin again.
    btw, there are others here who have been thru this. i'll try and round some up so they can help with their experiences
