Parents' concerns

My mother has diabetes, and it's been over 10 years.

Your stomach condition is not good due to complications, and your physical strength is poor.

For several years, I have been walking more diligently to improve my physical strength, so my stamina has slightly improved. However, if I stand for a long time, I sometimes feel exhausted and need to lie down. It's not sweating, just a lack of strength in my body, and if I lie down or sit for a moment, I feel better. I'm not sure if this is due to diabetes or if there is another cause.
