Extraintestinal manifestations of Crohn's disease include fever or nutritional disorders. When there is a fever, symptomatic fever-reducing treatment should be applied using antipyretic medications. If the body temperature does not exceed 38°C, physical cooling methods can also be used, such as wiping the palms of the hands, soles of the feet, forehead, armpits, and groin with alcohol or a warm towel to dissipate heat physically.

It is important to drink plenty of water and consume more vegetables to maintain hydration. Attention should also be given to enhancing nutrition by providing a high-nutrient, low-fat diet, which could include lean meats, eggs, and fish. Strict rest is crucial during the disease flare-ups to avoid excessive fatigue.
