Dietary Care After Severe Influenza

Dear YY: Influenza is an acute viral respiratory illness that commonly causes fever, headache, muscle pain, fatigue, runny nose, sore throat, and cough, but typically resolves within 2 to 7 days.
Clinically, conditions referred to as the common cold, laryngitis, bronchitis, viral pneumonia, and undifferentiated acute respiratory illnesses may all be caused by infection with the influenza virus.
It is estimated that during seasonal outbreaks, about 10% of infected individuals may experience gastrointestinal symptoms such as nausea, vomiting, and diarrhea alongside respiratory symptoms.
The significance of influenza lies in its rapid outbreaks, widespread transmission, and severe complications, particularly bacterial and viral pneumonia.
During outbreaks, severe cases and fatalities are more commonly seen in the elderly, as well as in individuals with heart, lung, kidney, and metabolic diseases, or those with compromised immune function.

Your family member has experienced a challenging course of treatment due to severe complications, and physical weakness is to be expected.
In addition to maintaining good control of basic health parameters such as blood pressure and blood sugar, a balanced diet that provides sufficient calories and protein is essential for recovery.
I wonder how their appetite is? Ideally, if they can consume one bowl of cooked rice, about 100 grams of lean meat (chicken, fish, eggs, or tofu), and one bowl of vegetables (cooked green, yellow, white, red, and black varieties) at each meal, along with snacks like dairy products, fruits, or high-calorie pastries, that would be beneficial.
The amount of snacks should not interfere with the balance of the main meals.
Commercially available adult nutritional formulas can be used to enhance nutritional intake, and you may inquire with a hospital dietitian for guidance on their use.
Nutritional supplementation takes time, so it is important to focus on eating each meal mindfully without needing to rely on any specific nutrient.
Wishing for a speedy recovery.

Sincerely,
Dietitian Tang Weili

More Info

Recovering from severe influenza, especially after an extended hospital stay, can be a challenging process. The body has gone through significant stress, and it is essential to provide it with the right nutrients to facilitate healing and regain strength. Here are some nutrition tips and recommendations for recovery after severe influenza:
1. Balanced Diet: Focus on a well-rounded diet that includes a variety of food groups. This should consist of:
- Proteins: Essential for tissue repair and immune function. Include lean meats (chicken, turkey), fish, eggs, dairy products, legumes (beans, lentils), and nuts. Aim for at least 1.2 to 2.0 grams of protein per kilogram of body weight, depending on the severity of the illness and recovery needs.

- Carbohydrates: Provide energy necessary for recovery. Opt for whole grains (brown rice, whole wheat bread, oats), fruits, and vegetables. These foods also provide fiber, which is important for digestive health.

- Fruits and Vegetables: Rich in vitamins, minerals, and antioxidants, these foods help support the immune system. Aim for a colorful variety to ensure a broad spectrum of nutrients. Foods high in vitamin C (like oranges, strawberries, and bell peppers) and vitamin A (like carrots and sweet potatoes) are particularly beneficial.

2. Hydration: Staying hydrated is crucial, especially if there has been any fever or respiratory distress. Water is the best choice, but you can also include herbal teas, broths, and electrolyte-rich drinks. Avoid caffeinated beverages, as they can lead to dehydration.

3. Nutritional Supplements: If appetite is poor or if it’s challenging to meet nutritional needs through food alone, consider using nutritional supplements. Commercially available nutritional shakes or powders can provide a concentrated source of calories and protein. Consult with a healthcare provider or a registered dietitian to choose the right product.

4. Specific Nutrients:
- Zinc: Important for immune function and may help in recovery. Foods rich in zinc include meat, shellfish, legumes, seeds, nuts, dairy, and whole grains.

- Vitamin D: Supports immune health. Sun exposure is a natural source, but it can also be found in fortified foods and fatty fish. A supplement may be necessary if levels are low.

- Omega-3 Fatty Acids: Found in fish oil and flaxseeds, these can help reduce inflammation and support recovery.

- Probiotics: These beneficial bacteria can help restore gut health, especially after antibiotic use. Yogurt, kefir, and fermented foods are good sources.

5. Small, Frequent Meals: If appetite is low, try eating smaller, more frequent meals throughout the day rather than three large meals. This can help ensure adequate nutrient intake without overwhelming the digestive system.

6. Monitor Symptoms: Keep an eye on any symptoms that may arise during recovery, such as persistent fatigue, shortness of breath, or changes in appetite. These may require medical attention.

7. Consult a Professional: Given the complexity of recovery from severe influenza, especially with complications like pulmonary edema, it is advisable to work with a healthcare provider or a registered dietitian. They can provide personalized recommendations based on individual health status and recovery needs.

In summary, recovery from severe influenza requires a comprehensive approach to nutrition, focusing on a balanced diet rich in proteins, carbohydrates, vitamins, and minerals, along with adequate hydration. Taking the time to nourish the body properly will support healing and help regain strength.
