- Tests for your heart, like an EKG or echocardiogram

What to expect at your appointment
Your doctor will work with you to understand your symptoms. They may refer you to specialists like a lung doctor, heart doctor, or a rehabilitation team. The process can take time, so be patient with yourself.
Treatment
Treatment for Long COVID focuses on managing your symptoms and improving your quality of life. There is no one-size-fits-all cure, but many people benefit from a combination of therapies.
Self-care at home
- Pacing – plan your activities and rest before you get too tired
- Gentle exercise like walking or stretching, but stop if you feel worse
- Good sleep habits – go to bed and wake up at the same time
- Manage stress with deep breathing, meditation, or talking to someone
- Healthy eating to support your energy and immune system
Medical treatments
Your doctor may recommend treatments such as physical therapy to help with strength and breathing, occupational therapy to help with daily tasks, or talking therapy for anxiety or depression. Some people may be referred to a specialist clinic for Long COVID. Your doctor will work with you to find what helps.
Living with this condition
Living with Long COVID means finding a balance between activity and rest. Some days you may feel better, other days worse. It is important to listen to your body and not push yourself too hard. Plan your important tasks for when you have the most energy.
Lifestyle tips
- Rest when you need to, and do not feel guilty
- Stay connected with friends and family, even if it is by phone or video
- Ask for help with chores or errands when you need it
- Consider joining a support group online or in person
Diet and exercise
Eat a balanced diet with plenty of fruits, vegetables, and protein to give your body the nutrients it needs. For exercise, start slowly with gentle walking or stretching. If you feel more tired or breathless after activity, take more rest. Your doctor or a physiotherapist can help you create a safe exercise plan.
Mental health and emotional wellbeing
It is normal to feel frustrated, sad, or anxious when you have Long COVID. The uncertainty and daily challenges can affect your mental health. Talk to your doctor or a counselor if you are struggling. If you feel like hurting yourself, call a crisis helpline right away. You are not alone.
Prevention
The best way to prevent Long COVID is to avoid getting COVID-19 in the first place. This includes washing hands, wearing masks in crowded places, and staying up to date with vaccines.
