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 ankles, knees and joints of the feet often are the first joints affected by reactive arthritis. Reactive arthritis also can cause inflammation of the tendons, including the Achilles tendon at the back of the ankle.
