Hello,
Your mother is suffering from
weight loss and is passing blackish poop, she has also lost weight. Blackish stool may be indicative of bleeding
gastric ulcers, esophageal and gastric cancers. Get your mom clinically assessed by a GP, get her all required blood works and investigations done.
She will be accordingly given conservative treatment or may be recommended surgery. Her treatment will depend on the diagnosis made. In the meantime , she can take laxatives for easy bowel movement, she should take adequate amount of fluids and water to stay well hydrated. Staying hydrated will help in better bowel movement. Taking antacids will help reduce gastric problems.
She should get a complete medical check up done. Taking digestives and
liver tonic will help in liver repair. She needs investigations (blood tests and imaging tests) done for liver and lungs. Her treatment will depend on the pathology detected.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K., General & Family Physician
