Hi, Welcome to Health care magic forum.
Diabetes is a disease due to lack of
insulin, which enhances the absorption of the carbohydrates, and give energy and storage in the tissues.
When there is diabetes, this process is hampered, and the storage is obstructed.
When the drugs are used the sugars you take are absorbed and stored and and cause weight gain,if you go on taking more calories, the blood sugar is also show high levels.
First thing you have to do is the diet restriction, mainly calories, and practice exercises, and modify the drugs according to the test results, till the normal results are seen.
Wishing for a quick and complete recovery. Thank you.
