Hello,
Welcome to Health Care Magic. I read carefully your query and I understand your concern.
The types of blood in the stool are red, black or occult; the different colors of blood determine the level of disease in gastrointestinal tract.
If you see red blood in the stool these mean that you have
rectal bleeding.Rectal bleeding causes are: hemorrhoids,
anal fissure,
diverticulitis,
colon cancer, polyps, and colitis.
I see that you are overweight, overweight lead to hemorrhoids problem, is one of risk factors, you should
weight loss to prevent not only this problem but the other that can induce overweight in the next future.
The bleeding in your age probably is from hemorrhoids or anal fissure that are linked in with the lifestyle and diet, you should prefer a diet with vegetable, fruits, fiber and drink minimally 8 glass of water, this diet regime help your bowel movement and avoid
constipation that can lead to anal fissure and to blood stool and also you should continue the sport activity because it help to prevent a lot of health problem.
To determine the cause of your problem you should go to a gastroenterologist and do additional examination like
colonoscopy.
Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions.
Kind regard,
