Thanks for your question on HCM. I can understand you problem and worry. You can follow these steps for better control of diabetes in your husband. 1. Diet modification. Avoid sugar in everything like milk, juice etc. Eat more and mor le green leafy vegetables. Give him high fiber diet. High fibers can give you feeling of full stomach so further food intake can be avoided. Avoid large meals, instead give him frequent small meals. Avoid high calorie diet like oily, cheesy food. 2. Regular aerobic exercise in the form of brisk walking, jogging or trade mill. Go for walk after meals. This will increase metabolism and reduce post meal sugar spike. 3. Take insulins regularly. You can also give long acting insulin (24 hours action) to prevent day time fluctuations and provide glycemic control throughout the day.
