If i have sjogren's and am obese does that mean that my immune system is weak or compromised? am i at an increase risk for covid or a worse outcome?

Sjogren’s is an autoimmune disorder which means you make abnormal antibodies but this does not necessarily mean your immune system is compromised. Sometimes, the medicines used to treat autoimmune disorders causes some immunosuppression so this should be discussed with your doctor when you are being prescribed medication treatment. Obesity is a risk factor for Covid severity so get vaccinated.
