Some foods may be easier to tolerate when digestive symptoms such as diarrhea, bloating or constipation occur, but there is no single diet that treats every gastrointestinal problem.
The appropriate food choices depend on the cause of the symptoms. Acute diarrhea, for example, can result from infections, food poisoning, medicines and other conditions. People with persistent or recurring symptoms should speak with a health professional rather than relying on food changes alone.
Papaya
Papaya can be part of a balanced diet and is listed by Monash University among fruits that can be suitable in a low-FODMAP eating pattern, depending on serving size. Low-FODMAP diets are sometimes used under professional guidance to manage symptoms associated with irritable bowel syndrome, including bloating, abdominal pain and altered bowel habits.
However, there is not enough evidence to describe papaya itself as a treatment for IBS or constipation. People with digestive symptoms should pay attention to how individual foods affect them rather than assuming a particular fruit will relieve the problem.
Rice and oats
Plain rice can be a reasonable food when someone has diarrhea and is able to eat. The National Institute of Diabetes and Digestive and Kidney Diseases lists plain rice among soft foods that can be eaten during diarrhea.
Oats may also be tolerated by some people, although individual responses vary. A person with acute diarrhea does not generally need to fast or follow a highly restricted diet. Once appetite returns, most people can gradually return to their normal diet while replacing fluids and electrolytes lost through diarrhea.
Berries and some citrus fruits
Fruit can affect people with digestive disorders differently. Certain fruits contain excess fructose, a type of carbohydrate that can be poorly absorbed by some people and may contribute to bloating, gas or other IBS symptoms.
Monash University’s low-FODMAP guidance lists several berries and citrus fruits, including strawberries, blueberries and oranges, among foods that can be suitable depending on serving size. This does not mean they will relieve symptoms for everyone.
Probiotic foods
Probiotics are live microorganisms found in some fermented foods and dietary products. Research suggests that certain probiotic preparations may reduce the risk of diarrhea associated with antibiotic use, but the evidence varies by probiotic strain, condition and individual.
That means a probiotic drink should not be presented as a general treatment for digestive problems. Some people may benefit from particular probiotic products, while others may not. People with serious underlying illnesses or weakened immune systems should discuss probiotic use with a health professional because risks can be greater in these groups.
What about carbonated drinks?
Carbonated drinks should not be recommended as a treatment for an upset stomach. In people with diarrhea, some soft drinks may actually make symptoms worse, particularly when they contain caffeine or large amounts of simple sugars.
For diarrhea or vomiting, replacing lost fluids and electrolytes is more important. Water, broths and appropriate oral rehydration solutions can help prevent dehydration, depending on the severity of the illness.
Food can sometimes make digestive symptoms easier to manage, but it does not replace medical evaluation when symptoms are persistent, severe or recurring. The cause of the problem matters, and what helps one person may worsen symptoms in another.
