Ulcers are wounds that can occur in different places in the body. They are mostly caused by bacteria infections and can be painful and discomforting.
However, most ulcers heal completely when treated early and properly.
There are different types of ulcers sharing similar causes and symptoms, and you may not be able to differentiate between these symptoms until you visit your doctor. For instance, esophageal ulcers and stomach ulcers share similar causes and symptoms. Seeing a healthcare professional is the only way to ensure you get proper diagnosis and treatment.
Also, some ulcers can result from underlying health conditions, leading to more severe conditions when not treated.
In this article, we'll discuss the different types of ulcers and their causes. We'll also talk about when to see a doctor for ulcer-related issues.
Ulcers are wounds or sores that occur in different parts of the body. They are wounds that take a long time to heal because of abnormal or insufficient blood supply, nerve damage, or wound infection.
Some ulcers occur in visible parts of the body, like your leg and hands, while some can occur in the internal parts of the body, such as the gastrointestinal tract.
Ulcers can become infected when not treated properly. There are different causes of ulcers; likewise, their treatments vary depending on the cause and type of ulcer.
Some of the common types of ulcers include:
Leg and foot ulcers are open wounds or sores that form in your leg and foot. Sometimes this leads to infections and gets severe when not treated. Leg ulcers most times don't cause pains, especially when it occurs due to some nerve problems. And because of that, those affected may not go for treatment. The result is that the ulcer worsens, leading to an infection.
People with health conditions like diabetes, kidney disease, infections, and high cholesterol are at higher risk of developing leg and foot ulcers.
Leg and foot ulcers can be categorized into neurotrophic or arterial ulcers.
Neutrophils are phagocytes that trap microorganisms present in wounds, killing them. However, when produced at high levels, it can lead to the development of neutrophilic ulcers.
This type of ulcer affects people with impaired foot sensation, although it commonly affects people with diabetes. It doesn't cause pain but can lead to complications when not treated.
Arterial foot ulcers occur when there is reduced blood flow to your leg through the arteries. People with diabetes and those who smoke are more prone to arterial ulcers. Arterial ulcers can occur on your heels, tips of your toes, between your toes, and on your nail bed.
Some of the common causes of leg and foot ulcers include:
Complications of foot ulcers are common among people with untreated foot ulcers and those with health conditions such as diabetes. When left untreated for long, leg and foot ulcers can lead to complications like skin infection, foot amputation, gangrene, sepsis, and leg and foot deformities.
Stomach ulcers are painful sores that affect the lining of the stomach and intestines. A stomach ulcer, also called a gastric ulcer, is a type of peptic ulcer disease (ulcers that affect the inner lining of the lower esophagus, the stomach, and the small intestine).
Contrary to popular belief, skipping meals does not cause stomach ulcers. Rather, stomach ulcers occur when digestive acids damage the stomach lining and the thick layer that protects the stomach.
Some stomach ulcers can go unnoticed for a long time until it starts causing severe symptoms like bleeding. However, it's rare to develop such stomach ulcers.
In more common cases, stomach ulcers can cause the formation of holes in the stomach wall. They can also present with symptoms like weight loss, nausea, bloating, constipation, heartburn, and pain in the upper abdomen.
While foods do not directly cause stomach ulcers, foods play a role in worsening or reducing the symptoms. If you have stomach ulcer, it will be helpful to find out the foods that promote stomach ulcer healing and are good for ulcer patients.
There are two main causes of stomach ulcers:
When not treated, stomach ulcers can lead to a stomach infection and increased pain.
An esophageal ulcer is a sore in the lining of the lower part of the esophagus. It is also a type of peptic ulcer.
The esophagus is the narrow tube that connects the throat to the stomach. Esophageal ulcers typically occur at the lower part of the esophagus - the junction between the stomach and esophagus.
Symptoms of esophageal ulcers include indigestion, nausea, bloating, lack of appetite, heartburn, and vomiting. Some people also experience esophageal ulcers without any obvious symptoms.
People at more risk of developing esophageal ulcers are people who constantly take alcohol, people with too much calcium in their blood, or those who take steroids often.
Esophageal ulcers share similar causes as stomach ulcers. Causes of esophageal ulcers include:
An eye ulcer (corneal ulcer) is also known as keratitis. It is an ulcer or sore that occurs in the cornea, the clear layer over the iris (2) This type of ulcer is common in people who wear contact lenses.
