Hello,
Uncontrolled diabetes over a period of years results in various complications and damage to almost all the organs of body including heart,eyes,kidneys,nerves,blood vessels etc.
Your husband has already had by pass surgery and having bad kidneys.
Once
chronic kidney disease sets in,the pace of deterioration of overall health gains speed.
It is high time that your husband quits sweets,alcohol and starts taking proper medications along with dietary control.
Even if he becomes sincere now,he can add some life otherwise all these signs are very bad.
The problem is that controlling diabetes is not just taking medications only,it involves total participation of the person.Once the person himself is not interested in his life,very sorry to say that nothing can be done.
May god bless you and your husband and pray to the god that he starts thinking rationally and correctly.
Thanks
