Are there any lifestyle modifications that can help prevent parasitic infections in older adults?

What are Parasitic Infections?

Parasitic infections are caused by tiny organisms, such as protozoa and worms, that live in or on another living organism. These parasites live off their host, taking nutrition and energy from them in order to survive. While these organisms can cause varying types of biological damage, the elderly are particularly susceptible to the negative effects of parasitic infections.

Common Parasitic Infections in Elderly Patients

Seniors are especially vulnerable to parasitic infections, due to weakened immune systems, poor hygiene practices, poor nutritive diets, and the presence of underlying medical conditions. Common types of parasitic infections in elderly patients include Giardia, Ascaris, Cryptosporidium, and Strongyloides. Symptoms of these infections can vary but can include cramping, fever, chronic diarrhea, and vomiting.

Diagnosing and Treating Parasitic Infections in Elderly Patients

If an elderly patient is suspected of having a parasitic infection, it’s important to seek medical attention right away to get the proper diagnosis and treatment plan. To diagnose the infection, the doctor may take a more detailed medical history, perform a physical exam, and then employ laboratory tests, such as fecal tests, to confirm the presence of parasites.


Once the infection is confirmed, the next step is to get the patient started on the proper drug therapy for the particular type of parasitic infection. The most commonly prescribed medications include antiparasitic drugs, such as metronidazole, albendazole, praziquantel, and ivermectin, that can be taken orally or intravenously. It’s important, however, to make sure that the elderly patient is aware of possible drug side effects and takes the necessary precautions to reduce the risk of experiencing complications.

Dietary Guidelines

In order to help an elderly patient recover quickly and completely from a parasitic infection, it’s vital that they adhere to certain dietary guidelines. An individualized diet plan should be based on the health of the patient, the severity of the infection, and the goals of the treatment. Generally speaking, diets should be rich in essential vitamins and minerals and should also include foods that are known to reduce inflammation and boost immunity, such as garlic, kiwi, papaya, walnuts, and dark, leafy greens. Drinking plenty of fluids and limiting the intake of caffeine, refined sugars, and processed foods is also recommended.

Preventing Parasitic Infections in Elderly Patients

The best way to treat a parasitic infection in an elderly patient is to prevent the infection from occurring in the first place. To do this, it’s important to reduce risk factors associated with parasitic infections, such as limited access to clean water, poor sanitation, and poor hygiene habits. Additionally, it’s important to ensure that the elderly patient is receiving an adequate nutritive diet and that their living environment is kept clean and free from potential sources of contamination.

By understanding the risk factors, symptoms, and treatments associated with parasitic infections in elderly patients, seniors and those caring for them can take the necessary steps to reduce the risk of contracting this type of infection and mitigate its potential effects.
