Although many patients tolerate Wegovy, others have reported serious adverse events. Alleged complications include gastroparesis (stomach paralysis), intestinal blockage, pancreatitis, gallbladder disease, and sudden vision impairment such as Non-Arteritic Anterior Ischemic Optic Neuropathy (NAION). Symptoms may involve chronic nausea and vomiting, severe abdominal pain, malnutrition, emergency hospitalizations, or, in some cases, persistent effects even after discontinuing the medication. The severity and duration of these complications can vary depending on individual health factors and medical history.
