It is not possible to generalize which of the two diseases is better to treat, but it should be treated according to the condition and in accordance with the doctor’s instructions. Esophagitis refers to the inflammation of the esophageal mucosa caused by edema and congestion due to irritation or injury. The cause of esophagitis is gastroesophageal reflux (GERD), due to the impaired function of the anti-reflux barrier such as the relaxation of the lower esophageal sphincter, the gastric contents can reflux into the esophagus resulting in damage to the esophageal mucosa. Carditis is an inflammation that occurs in the cardia of the stomach, and the main causes are Helicobacter pylori infection, duodenogastric reflux, and autoimmunity. Esophagitis can be relieved by improving lifestyle habits, i.e., do not eat full meals and do not lie down after meals, etc., or by giving acid-suppressing agents such as omeprazole and rabeprazole. And carditis not only need to improve lifestyle habits, but also need to be treated according to the specific cause, such as Helicobacter pylori have standardized quadruple drug, that is, two kinds of antibiotics such as amoxicillin and clarithromycin + bismuth + proton pump inhibitors such as omeprazole combined, autoimmune diseases need immunosuppressive therapy such as prednisone. When diagnosed with esophagitis or carditis, patients are advised to consult the gastroenterology department of regular hospitals in a timely manner, and under the guidance of professional physicians for treatment, and avoid self-medication to avoid adverse consequences.
