Oranges are often seen as one of the healthiest fruits — packed with vitamin C, fiber, and antioxidants that support the immune system and skin health. But while they can do wonders for many people, not everyone benefits from eating them regularly. In some cases, their acidity, sugar, and mineral content can actually make certain health conditions worse. Here’s who should think twice before reaching for an orange.
People with acid reflux or GERD
The natural citric acid in oranges can irritate the stomach and esophagus, worsening reflux symptoms. For people with GERD, eating oranges—especially on an empty stomach—can trigger heartburn and discomfort. Choosing low-acid fruits like bananas or papayas can be a gentler alternative.
Individuals with kidney disease
Because oranges are rich in potassium, they may be risky for those with chronic kidney disease. When kidneys can’t properly filter potassium, it can build up in the bloodstream, potentially causing muscle weakness, irregular heartbeat, or even life-threatening complications. Patients should discuss potassium-rich fruits with their doctor before including them in their diet.
People with citrus allergies
Some people are allergic to the natural proteins in oranges, which can cause itching, rashes, swelling, or digestive discomfort. In severe cases, allergic reactions may affect breathing or trigger inflammation. Anyone experiencing these symptoms should avoid citrus and seek professional medical advice.

Those who frequently experience heartburn
Even if you don’t have GERD, oranges can still aggravate the esophagus due to their high acid content. Eating too many acidic fruits can relax the valve that keeps stomach acid where it belongs, leading to a burning sensation in the chest. Alkaline fruits like apples or melons can help neutralize acidity.
People with chronic constipation
Though oranges are known for their fiber, eating too many without enough water can backfire. Fiber needs hydration to move smoothly through the digestive system, otherwise it can harden stools and worsen constipation. Balance citrus intake with plenty of fluids and hydrating fruits such as kiwi or papaya.
Individuals with sensitive stomachs
Those prone to stomach irritation or gastritis should limit acidic foods like oranges. The high acidity can inflame the stomach lining and cause pain or nausea, particularly if consumed first thing in the morning.
People managing blood sugar levels
Despite being a natural source of sugar, oranges can still raise blood glucose levels quickly. People with diabetes or insulin resistance should monitor portion sizes and pair citrus with protein or healthy fats to balance absorption.

Anyone taking certain medications
Some prescription drugs, including blood pressure medications, may interact with citrus fruits. Compounds in oranges can affect how the body processes these drugs, altering their effectiveness. Always consult your doctor before combining medication with large amounts of citrus.
Those prone to mouth sores
For people who regularly get mouth ulcers or cold sores, oranges can sting and irritate the area, slowing healing. Opting for milder fruits may reduce discomfort and promote recovery.
Individuals prone to dehydration
While oranges contain water, their acidity and mild diuretic effect can sometimes increase fluid loss in sensitive individuals. This can contribute to headaches or fatigue, especially when combined with caffeine or salty foods.
People with dental sensitivity
The acid in oranges can erode tooth enamel over time, leading to sensitivity or decay. To protect teeth, rinse your mouth with water after eating citrus or enjoy them as part of a meal instead of on their own.
