this is for my son who lives out of state and his wife was talking to me about his recent episodes. He is a pilot and on his day off, he washed his car and polished it and took a long walk and when he got home, he said his hands were shaky and he felt faint. He thought he had a low blood sugar reaction as I have diabetes (mother) and he ate a bunch of candy and said he felt better after that. I guess he has a few of these episodes and he drinks a lot of juices and has to get up several times at night to urinate.
Hello, As per your history, it may be due to hypoglycemia. For that, you may require fasting and postprandial sugar levels after consultation. Do regular blood sugar monitoring. Take a balanced diet.  Take medication just before food. During shakiness take a teaspoon of sugar. Hope I have answered your query. Let me know if I can assist you further.
