Colon cleansers such as laxatives are not recommended for diverticulosis or colitis, two common forms of colonic infection. Instead, hydration is recommended for colitis, and a high-fiber diet is recommended for diverticulosis, according to WebMD and MedicineNet.
The initial treatment for colitis focuses on managing pain and stabilizing vital signs. Rehydration is next for those patients who are particularly dry. If patients cannot manage fluids orally or if they have anomalies in their electrolyte levels, intravenous fluids may be needed, notes MedicineNet.
Diverticulosis patients who have no complications only need a high-fiber diet to keep more diverticula from forming. However, surgery may be necessary if diverticulosis leads to colonic perforation, as waste can leak into the abdominal cavity, reports WebMD.
