symptoms of stomach bleeding
Bleeding may also occur within the spinal canal and affect spinal cord function. Intra-abdominal bleeding may be hidden and present only with pain, but if there is enough blood loss, the patient may complain of weakness, lightheadedness, shortness of breath, and other symptoms of shock and decreased blood pressure. Once again, the symptoms depend upon where in the abdomen the bleeding occurs. If there is bleeding in the stomach, the patient may vomit bright red blood, or if it has been in the stomach for a period of time, the vomit may look like coffee grounds.
