Hello, Sometimes, due to side effect of medicines, a person may sleep excessively. Sleeping all the time can indicate a loss of a zeal for living, depression, family struggles, financial stress, etc. Get your mother clinically examined by a GP, get her checked for diabetes, bed sores, muscle atrophy, cardiovascular decline, etc. Get a complete medical check-up done. You may need to keep medical attendants / nurse for her so that she is well cared for and fed. They can make her do few exercises and do all required for the needful. For arthritis, do continue to give her the prescribed medicines. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Nupur K., General & Family Physician
