The term SIBO stands for Small Intestinal Bacterial Overgrowth. This is a condition in which the small intestine has an excessive amount of bacteria. This bacteria can cause severe symptoms in the dog. It’s also very common in dogs with diabetes, especially Type 1. There are several reasons why this bacteria is so common in dogs with diabetes. One reason is that their pancreas may not be producing enough insulin.

Another reason is that their small intestines may not be absorbing the insulin properly. If they are not getting enough insulin in their bloodstream, they will need to take more insulin to cover their bodies’ needs. 

This means that they may have to take larger doses of insulin than they would normally need. These large doses of insulin can cause a lot of problems. The excess insulin can cause problems with their kidneys, liver, and blood sugar levels. 

In addition, if they have too much insulin in their bloodstream, it can cause a problem with their fat cells. Their fat cells can become insulin resistant and not absorb the insulin as well. This can cause them to gain weight and even become diabetic again.

What causes sibo in dogs

SIBO in dogs is caused by bacteria overgrowth in the small intestine. The most common bacteria found to cause SIBO in dogs are Escherichia coli, Enterococcus faecalis, Klebsiella pneumonia, and Streptococcus pneumonia.

The presence of SIBO can lead to a variety of symptoms in dogs, including diarrhea, vomiting, foul-smelling gas, abdominal pain and swelling, and weight loss. Treatment for SIBO usually involves antibiotics to kill the bacteria overgrowth, followed by a period of probiotic therapy to help restore balance to the gut flora. (Read full Article Here)
