14. Vomiting blood
We didn’t list vomiting blood at first because it is often a late consequence of a complication of acid reflux, especially in the case of a peptic ulcer. However, vomiting blood is one of the classic signs of a peptic ulcer because internal bleeding of the ulcer is often the first complication to arise.
Internal bleeding is a common complication, primarily when the ulcers are near blood vessels. Vomiting blood is the sign of a rapid and severe hemorrhage that’s very profuse and cannot be contained by the stomach.
There are other causes of vomiting blood, but peptic ulcers are one of the most common. Still, it is necessary to perform an endoscopy to diagnose the problem and stop the hemorrhage. Thus, if you’re vomiting blood, you should not wait for it to stop or take medications. Instead, seek urgent medical assistance to solve your health problems immediately.
