Over the course of two days my stools have turned from a normal

This answer was rated:

Over the course of two days my stools have turned from a normal colour to black, I have no noticeable discomfort but my stomache is making noises, further about two weeks back I had for the first time ever very severe constipation. I will see my GP to tomorrow, do I need to see some one sooner. I am not taking any supplements, and my diet is more or less unchanged.
Hi. Welcome to JustAnswer. I shall try my best to assist you while you are corresponding with me.
Black stools are usually a sign of upper GI bleeds, from peptic ulcers, variceal bleeds, bowel ischemia etc.. However, sometimes, iron containing supplements can also cause black stools. The most important thing to note is, that if the stools are tarry and jelly like then it is clotted and hemolyzed blood coming from the upper GI. If they are normal in consistency but of black color then they are likely to be due to food colors, iron supplements, peptobismol etc.
Since, your stomach is making growling sounds and you have black stools the possibility of peptic ulcer and gastritis should be kept in mind but you should also know that if you are taking a supplement with iron in it then both these symptoms can be caused by that supplement.
In brief, if you think that the stools are increasing in frequency and the stools are jelly like and tarry, if there is abdominal pain, fever, nausea, vomiting, loss of appetite, then you should see a physician as soon as possible, in an ER or an Urgent care.
Hope this helps.
