My grandfather is a farmer, and he only knows hard work. He has been diagnosed with blood sugar for the last 20 years. But he is not taking any medication he manages it with diet and hard work. Blood sugar is always under control but 6 months ago he had a typhoid which he had every year we think it is because of working in the field but after typhoid he feels very weak and he is having muscle pain and after a little work he gets tired. He had many tests but all were normal We consulted with many doctors but his condition is the same as it was earlier. What other test should we have and what diet should he follow and what medication should he have? Please 🙏 look into this case.
