Sarcoidosis is an inflammatory disease that forms lumps, commonly know as granulomas. It usually starts in the lungs, skin, lymph nodes, but can occur in any organ throughout the body. It is generally unknown what causes sarcoidosis, but experts believe it results from the body’s immune system responding to infectious substances.

The symptoms of sarcoidosis vary depending on which organ is affected. General symptoms can include fatigue, swollen lymph nodes, weight loss or painful joints. Symptoms of sarcoidosis of the lung, where it is most commonly found, will produce a persistent dry cough, chest pain or wheezing. In the skin, symptoms will include a rash around the shins or ankles, which consists of reddish bumps and is warm to the touch, growths under the skin- called nodules, lesions or patches which are darker or lighter in colour.

Sarcoidosis can affect the eyes, and although it may not produce symptoms. Blurred vision, eye pain, itchy or dry eyes, redness and a sensitivity to light are all signs that you may have sarcoidosis and it is advised that you get your eyes checked.

Cardiac sarcoidosis, when the disease occurs in the heart can cause chest pain, shortness of breath, fatigue, irregular heartbeat, fainting, or swelling.

There is no treatment for sarcoidosis, and it will often go away on its own. Medications may be required to treat the symptoms. Topical corticosteriods, an anti-inflammatory drug, that is applied directly to the lesion in cream form or via drops to the eyes are usually the first treatment for sarcoidosis. Medications such as methotrexate and azathioprine, suppress the immune system and will reduce the inflammation.

Your condition will need to be monitored, to determine the effectiveness of the treatment. In some extreme cases, organ replacement will be required if the sarcoidosis has caused extensive damage to either the heart, lungs or liver.

In many cases sarcoidosis will disappear without treatment and patients will be able to continue to live a full life.
