It has been reported that some patients have been misdiagnosed with Diabetes, when in fact the correct diagnosis in their specific case was Sjogren's Syndrome.
Sjogren’s syndrome is an immune system disorder where the body attacks the mucous membranes and glands of the eyes and mouth that secrete fluids. Symptoms of Sjogren’s syndrome include dry eyes and mouth, joint pain, swelling and stiffness, swollen salivary glands, skin rashes and dryness, vaginal dryness, persistent dry cough and fatigue. Sjogren’s syndrome can be misdiagnosed as diabetes, lupus, rheumatoid arthritis, fibromyalgia, chronic fatigue syndrome, and multiple sclerosis.
