Digested blood from the upper gastrointestinal tract may appear black rather than red, resulting in "coffee ground" vomit or melena. [2] Other signs and symptoms include feeling tired, dizziness, and pale skin color. [18]
Premenopausal women with hematometra often experience abnormal vaginal bleeding, including dysmenorrhea (pain during menstruation) or amenorrhea (lack of menstruation), while postmenopausal women are more likely to be asymptomatic. [3] Due to the accumulation of blood in the uterus, patients may develop low blood pressure or a vasovagal ...

A complete blood count as well as an hemoglobin test should be performed when a patient presents symptoms of hematochezia. A colonoscopy may be necessary if there is suspicion of bleed from colon particularly in the elderly to look for the site and many causes of bleed like carcinoma, ulcerative colitis, rectal varices or other lesions and in certain instances upper gastrointestinal endoscopy ...
