Diarrhea can be a symptom of many different conditions, and if it persists, should be diagnosed by a vet. Home remedies are not recommended until a vet has definitively diagnosed the problem.
Some possibilities include food sensitivity and Inflammatory Bowel Disease.
When diarrhea is a problem, the possibilities for both dehydration and hypoglycemia increase[1]. The insulin dose you give depends partly on the meal being digested at a normal rate. When the food passing through the system speeds up in this manner, the insulin is still being absorbed at its usual rate[2]. It could mean that there's not enough food to match the insulin dose and a hypo could occur. You and your vet may want to temporarily decrease the insulin dose until you are both satisfied the diarrhea is under control.
