Hello dear, Lornoix (pharmacologically Lornoxicam) is a non steroid anti inflammatory drug. But it can cause pain abdomen if taken for a long time by inducing gastritis. The medications as prescribed by your doctor are correct, please take them as advised. Causes of Constipation include: 1. Functional cause- due to decreased gastric motility 2. Irritable bowel syndrome- constipation predominant type. 3. Less consumption of fiber rich foods 4. Less fluid intake 5. Prolonged use of certain medications. 6. Hormonal & Metabolic causes, etc. So, if the symptoms still persist, kindly consult a Gastroenterologist & get a proper physical examination done. Investigations like Ultrasound scan of abdomen, Colonoscopy & contrast studies will be helpful to rule out any pathology in the Gastrointestinal tract.
