1- If you suffer from kidney disease or diabetes and similar diseases where fasting will cause harm, you are allowed to break the fast. 2- The correct view regarding taking blood from veins for testing is that this does not break the fast, but if it is done often, it is better to leave it until night-time.

A person who is suffering from kidney failure should not fast on the days when he has dialysis, then if he can make up the fast he should do so. If he cannot make up the fasts because he is elderly and cannot fast, then he should not fast and should feed one poor person for each day.

These are the valid reasons for breaking the fast during Ramadan: 1- sickness, 2- traveling, 3 - pregnancy and breastfeeding, 4- senility and old age, 5- intense hunger and thirst, and 6- compulsion.
