For newly diagnosed or mild-to-moderate ulcerative colitis, the primary goal is to quickly calm inflammation and achieve remission. The most common and highly effective treatment options include: 1. Aminosalicylates (5-ASAs): Medications like mesalamine (taken orally or rectally as suppositories/enemas) are the standard first-line therapy to heal the colon lining. 2. Corticosteroids: Mild steroids like budesonide may be prescribed for short-term use to rapidly control active symptoms during a flare. 3. Lifestyle Support: Staying hydrated and avoiding trigger foods can significantly aid recovery. These therapies are very manageable and highly successful. Your doctor will help tailor the safest, most effective plan for you.
