Hiatal hernia does not usually cause weight loss, but acid reflux and dysphagia are the most common symptoms, which should be treated under a doctor’s supervision. Most small hiatal hernias do not cause obvious symptoms, while larger hiatal hernias are characterized by acid reflux, dysphagia, chest pain, epigastric pain, nausea, dry heaving, etc. In some cases, they may be accompanied by respiratory distress, or symptoms of gastrointestinal hemorrhage such as vomiting of blood or black stools. Wasting is usually seen in chronic wasting disease, and hiatal hernia is generally rare. However, it is important to note that if the hiatal hernia persists for a long time and affects the digestive function, further wasting may occur due to the imbalance of energy supply and demand. Therefore, if wasting occurs, it is important to consult a doctor to find out the cause of wasting, and not to make blind judgment and dispose of it on one’s own in order to avoid inappropriate intervention and adverse consequences.
