Sarcoidosis: evolution and complications

Sarcoidosis may follow an acute or chronic course. In both cases, the chances of recovery are generally good. The prognosis and possible complications nevertheless depend on the affected organ.

The evolution

Although acute sarcoidosis may be manifested by violent symptoms, the prognosis is rather favorable: in about 95% of cases, acute sarcoidosis experiences a spontaneous recovery, without treatment, within 4 to 6 weeks. After a few months, those affected often recovered. One year at the latest, all the consequences of the disease in the lungs have generally resolved.

For its part, chronic sarcoidosis can be cured by treatment with cortisone. Overall, the prognosis of chronic sarcoidosis is nevertheless less favorable than that of acute sarcoidosis: and the consequences can sometimes be very serious, especially when the brain or heart are affected, or if major problems affect the lungs. If in chronic sarcoidosis, new outbreaks occur regularly, it is advisable to consult a doctor and take his treatment.


In the case of chronic sarcoidosis, various complications may occur. Their shape and severity depend on the affected organ. Possible complications are for example: pulmonary fibrosis with respiratory failure, renal failure, long-term paralysis, vision problems.


It is impossible to prevent sarcoidosis, since the agents triggering the disease have not, to date, been clearly identified. If a member of your family has sarcoidosis, the risk that you will also be affected by the disease is slightly higher than in someone with no family history. In the case of monozygotic twins, the risk would even be increased by 30 to 50%. In these cases, it is recommended to be vigilant to identify possible symptoms of sarcoidosis as soon as possible. Also, do not hesitate to indicate a possible family history of sarcoidosis to your doctor in order to facilitate the diagnosis if necessary.
