You might also ask the doctor to order iron, TIBC (total iron binding capacity) and ferritin blood levels, as these can be abnormal before it ever shows up with an abnormal hemoglobin & you can have symptoms even if your hemoglobin is in normal range when your iron level is low. I know from experience.
Hi
Welcome to the forum!
Even a small hemorrhoid can bleed a lot, especially if the blood vessel is too superficial. Also since the blood falls with a splash in hemorrhoids, it scares the wit out of a person. There are hemorrhoidal creams available in the market which you can apply. Sit in a tub of warm water for 10 mins at least twice a day. Increase fiber in your diet. Eat lots of fresh fruits, vegetables, oats, porridge etc.
IBS and dysentery are the other possibilities that may or may not be associated. Since you are nauseous too, you should look at IBS too. Fatigue is expected with daily blood loss. Get your hemoglobin and stool test done.
Hope this helps. Please let me know if there is any thing else and do keep me posted. Take care!
