What is the ruling of the Sharia and the procedure in the event that a mother suffers from a neurological condition in her stomach that worsens with fasting, forcing her to break her fast and take medication?

If fasting is difficult for your mother due to illness and harms her, she has a concession to break her fast. She must make up for the missed fasts if she is able, even during winter days. However, if her illness is chronic and she has no hope of recovery, then she must feed a poor person for each day she breaks her fast. The approximate amount for feeding is one and a half kilograms of rice.
