Stomach ulcers affect the Nervous System. It agitates the nerves and often causes great pain. They can also affect the circulatory system because they erode major blood vessels, and can cause haemorrhages.
Ulcers are the painful reminders that tissue cells have died somewhere on the skin, on other external tissue, or on the lining of organs. These infected, open sores can continue to damage the tissue around them because they make tissue more vulnerable to damage. Ulcers can allow acid to eat through intestine walls to other organs or infect skin tissue down to the bone. Early treatment is a good way to prevent extensive damage.
