What Is Ischemia?

Ischemia is a condition that occurs when blood flow to a part of the body is blocked or restricted. This can happen for a variety of reasons, including:

* Atherosclerosis: Atherosclerosis is the buildup of plaque in the arteries, which can narrow the arteries and restrict blood flow.

* Thrombosis: Thrombosis is the formation of a blood clot in an artery or vein. This can also block blood flow.

* Embolism: An embolism is a piece of material, such as a blood clot, that travels through the bloodstream and blocks an artery.

* Vasospasm: Vasospasm is a sudden, temporary constriction of an artery. This can also restrict blood flow.

Ischemia can cause a variety of symptoms, depending on the location and severity of the blockage. Common symptoms include:

* Pain

* Numbness

* Tingling

* Weakness

* Paralysis

* Skin discoloration

* Coldness

* Loss of function

Ischemia can be a serious condition, especially if it affects the heart or brain. If you experience any of the symptoms of ischemia, it is important to see a doctor right away.

Treatment for ischemia

The treatment for ischemia depends on the cause of the blockage. Treatment may include:

* Medications to dissolve blood clots or prevent them from forming

* Surgery to remove plaque from the arteries

* Angioplasty to widen narrowed arteries

* Stenting to keep arteries open

Preventing ischemia

There are a number of things you can do to help prevent ischemia, including:

* Eating a healthy diet

* Getting regular exercise

* Maintaining a healthy weight

* Not smoking

* Controlling blood pressure

* Controlling cholesterol

* Managing diabetes

If you have any risk factors for ischemia, it is important to talk to your doctor about ways to reduce your risk.
