Hello I share your concern Blood in cough is a matter of concern and it warrnats detailed evaluation to find out underlying cause for it. It could be related to acute bronchitis, chest infection or heart disease. In my opinion you should consult your family physician or GP for physical examination and investigation like X Ray chest, blood test like hemoglobin, CBC, coagulation profile. Meanwhile take steam inhalation and be watchful if it occur again , collect and sample of sputum in strike bottle for microscopic examination. Loose motion with dark coloured stool might be suggestive of recurrent duodenal ulcer or duodenitis. In my opinion you should go for stool test for ova, cyst or protozoa and occult blood . twice a day motion is nothing to worry, it could be normal, You should take dietary fiber, fresh fruits and vegetables in your diet adequately. have plenty of fluids, ORS solution and fruit juices to counter dehydration and electrolyte imbalances. Hope I could answer your question, please feel free to ask for further clarification I will be happy to help you. Best wishes
