Nutrition during and after COVID-19

Nutrition and dietetics

For most, contracting COVID-19 will be a mild illness which might not impact on your food intake.

If you are self-isolating and have symptoms, it is important you maintain a regular and good intake of food and fluid, even if your appetite has been reduced.

If you have specific nutrition needs, it is important that you continue to follow the dietary recommendations made by you Dietitian or other healthcare professional. This may involve asking friends or family members to get you specific foods so you can continue to follow an appropriate diet.

The following information might be helpful for people whose food intake has been reduced by illness and / or have other pre-existing conditions affecting how much they can eat and drink.

Eating well helps you avoid malnutrition (undernutrition) losing weight, helps your body rebuild damaged tissues, fight infection and cope with the side-effects of treatment.

Experiencing a COVID-19 infection may also increase your risk of malnutrition, regardless of your body weight. Your ability to eat adequately to fight the infection and recover may be reduced due to symptoms such as:

  • Reduced appetite
  • Taste and smell changes
  • Feeling unwell e.g. generalised weakness, fatigue (tiredness)
  • Breathlessness and coughing

Are you at risk of malnutrition (undernutrition)?

If you were admitted to Cambridge University Hospitals NHS Trust:

You may be seen by a Dietitian during your admission, and / or contacted afterwards to help you recover.

In addition to written information entitled ‘High Energy, High Protein Diet’ and ‘Nourishing Drinks’, you may have been provided with some “oral nutrition supplements” or nutrition drinks when you were discharged from hospital.  These nutrition drinks provide extra energy (calories or kcal), protein, vitamins and minerals to help you recover from illness, maintain or gain body weight, if needed. It is important that you take the correct amount of these every day; if you cannot manage the amount directed by your Dietitian, please contact the Dietetic department.

The websites and links below provide a range of information for people to prevent or treat undernutrition, to aid recovery from a COVID -19 infection and sources of support for including volunteer schemes and food banks. We hope that you find this information helpful.
