People with acid reflux, kidney dysfunction, heartburn or chronic constipation should consult their doctor before eating citrus fruits.
Acid reflux
People with acid reflux should be careful when eating oranges and tangerines. Because this group of fruits has a high natural citric acid content, it can increase stomach acid, aggravating reflux symptoms. Stomach acid rising into the esophagus can lead to heartburn and chest discomfort. People with gastroesophageal reflux should choose low-acid fruits such as bananas, papaya, and melon to be good for the digestive tract.
Have kidney disease
Oranges are rich in potassium, which is necessary for muscle and heart function but is not suitable for people with chronic kidney disease. Weak kidneys will have difficulty filtering excess potassium from the blood, leading to hyperkalemia characterized by muscle weakness, fatigue, and abnormal heart rhythm. Severe hyperkalemia can be life-threatening, requiring emergency medical attention. Common symptoms include numbness, tingling, nausea, difficulty breathing, and become worse if left untreated.
Each person needs to adjust their diet, control their portions, and know the potential sources of potassium in food. Monitoring potassium intake and regular blood tests are necessary. Dialysis patients or kidney failure patients should consult their doctor before eating oranges.
Citrus allergy
Some people have citrus allergies due to their body’s sensitivity to certain natural compounds or plant proteins. Common symptoms include itching, hives, skin rash or swelling around the mouth. In severe cases, citrus allergies can cause difficulty breathing or indigestion. Anyone experiencing these symptoms should stop use and see a doctor to determine allergy and appropriate treatment.
Frequent heartburn
People who often suffer from heartburn should also be careful when eating oranges. The acidity of this fruit can irritate the esophagus, relax the lower esophageal sphincter (the muscle responsible for keeping food in the stomach from refluxing), causing discomfort and heartburn. Reducing your intake of oranges, lemons, and highly acidic fruits can control these symptoms. Adding alkaline fruits such as pears, apples, and watermelon helps enhance digestive health.
Chronic constipation
Oranges are rich in fiber, but eating too much without providing enough water can make constipation worse. People prone to constipation should drink enough water and eat 1-2 oranges a day. Eat more fruits that provide enough water such as papaya, kiwi, and cucumber to support digestive health.
