What kind of doctor treats Mesenteric Artery Ischemia?
A vascular surgeon usually treats mesenteric artery ischemia. In an emergency, emergency doctors and general surgeons may be involved first. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What it is
Mesenteric artery ischemia is a condition in which blood flow to the intestines is reduced or blocked. When the mesenteric arteries narrow or get blocked, the intestines do not get enough oxygen, which can cause pain and, over time, damage the bowel.
Symptoms
Sudden blockage causes severe belly pain that starts quickly. People may also feel nauseous, vomit, or have diarrhea. The chronic form develops slowly; its most common sign is belly pain after eating, and people often lose weight because they avoid meals.
Causes and who gets it
Most cases happen when fatty deposits build up inside the artery walls, a process called atherosclerosis. A blood clot can also travel from the heart and lodge in a mesenteric artery. The risk goes up with age, and is higher in people who smoke or have high blood pressure, high cholesterol, or diabetes.
How doctors diagnose it
Doctors start by asking about the pain and examining the belly. The most common imaging test is a CT scan, which takes detailed pictures of the blood vessels and organs and shows where the blockage is.
Treatment
Treatment depends on the cause. Sudden mesenteric ischemia is a medical emergency. Doctors may use medicines to dissolve clots, perform surgery to remove the blockage and repair the damaged bowel, or place a stent to hold the artery open.
Chronic mesenteric ischemia is often treated by opening the blocked artery with a balloon and stent, or with bypass surgery. Doctors also treat underlying causes and strongly encourage people to stop smoking.
When to see a doctor
Sudden, severe belly pain is an emergency; anyone with it should go to an emergency room right away. Belly pain that keeps coming back after meals, along with weight loss, also deserves prompt attention.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either kind can manage risk factors such as high blood pressure, high cholesterol, and smoking. When they suspect mesenteric artery ischemia, they refer the patient to a vascular surgeon.
Common questions
Is mesenteric artery ischemia the same as a heart attack?
It is similar in cause but happens in a different part of the body. A heart attack blocks blood flow to the heart. Mesenteric artery ischemia blocks blood flow to the intestines. Both are often caused by the same fatty buildup in the arteries.
Can it be prevented?
The risk can be lowered by not smoking, controlling blood pressure and cholesterol, and managing diabetes. These steps keep arteries healthier over time. Nothing removes the risk completely, but healthy habits usually help.
Why does eating cause the pain?
After a meal, the intestines need more blood to digest food. If the arteries are narrowed, they cannot supply that extra blood. The shortage of blood causes the pain.
Is the chronic form dangerous?
It can be, because it can lead to severe weight loss and malnutrition, which means the body does not get enough nutrients. In some people, a chronic blockage can suddenly become complete. That is why doctors usually recommend treating it rather than waiting.
