The simple answer here is eat less & exercise more. But it is not so simple. Diet & exercise are very important & should be a part of the program but other factors may also be in play. I do not know what meds you are taking but some of them do encourage wt. gain. Talk to your Dr. about that. A good med for you might be a GLP1. These drugs are injectable but usually depress appetite & cause wt. loss. Talk to your Dr. about going on one of this class of drugs. There are several with different injection patterns-2x/d, daily, or weekly. There are also wt. loss drugs available now that might help. The answer to the question "will wt. loss help the diabetes" is yes it will. The more overwt you are the more insulin resistant you become and the more meds you need. Some of the meds can stimulate appetite so you eat more & gain wt & need more meds. So 1) diet & follow it-see a dietician 2) set up a daily exercise program-The YMCA is a good place to start-but follow the program 3) talk to your Dr. about meds that fascilitate wt. loss particularly GLP1 drugs. Good Luck.
