I drank heavily on super bowl sunday- for the entire week i couldn't eat from an upset stomach and i have tarry stool. should i be worried? 30/f

Yes: Tarry stool indicates intestinal bleeding and you should see a doctor to get evaluated, and exclude disorders like peptic ulcer. Stay away from alcohol, it never did anybody any good ever. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex.
