Does swallowing blood invalidate fasting? My gums are very sensitive. Blood leaks between my teeth.

Dear Brother / Sister,

If the amount of blood that leaks between the teeth and goes to the throat is little and does not go in, it does not invalidate fasting. For, it is not possible to avoid it. If the amount is much but the majority of the liquid is saliva, it does not invalidate fasting.

However, if the majority of the liquid is blood, if the taste of blood is felt and if the amount of blood and saliva is equal, fasting is invalidated when it is swallowed. The same decree is valid for the tooth that is extracted. (Ömer Nasuhi BİLMEN, İslam İlmihali, s.294)

Besides, it is necessary to avoid squeezing the lips and the mouth, causing blood to come out. If you avoid it, the blood can be less than the saliva.

If bleeding is caused by a drug that is taken, it is necessary not to use that drug in Ramadan if it is not urgent, based on the advice of the doctor.
