Constipation is a side effect of lack of fiber in the low carb diet. Whole grains, legumes and fruit are the normal sources of dietary fiber, and they are all restricted on the Atkins diet's initial phases.
The type of treatment for reactive arthritis depends on the stage of reactive arthritis. The early stage of reactive arthritis is considered acute (early). Acute inflammation can be treated with nonsteroidal anti-inflammatory drugs (often referred to as NSAIDs). These drugs suppress swelling and pain.
The goal of treatment is to treat infections and manage symptoms. Since reactive arthritis may affect different parts of the body, more than one doctor may be involved in the patient's care. A rheumatologist (a doctor with specialized training in arthritis treatment) will likely be the primary doctor.
