Long COVID effects
Long COVID
Many individuals who recover from COVID-19 continue to face health challenges long after the initial infection subsides. This prolonged illness is referred to as long COVID or post-COVID-19 syndrome. Other terms you may encounter include long-haul COVID and post-acute sequelae of SARS-CoV-2 (PASC).
Currently, there isn’t a universally accepted definition of long COVID. In the United States, some experts describe it as a chronic condition triggered by the virus that causes COVID-19. Medically, this is known as an infection-associated chronic condition. As research continues, definitions and understanding of long COVID are likely to evolve.
Common Symptoms of Long COVID
Research has identified more than 200 potential symptoms associated with long COVID, which can vary in intensity. These symptoms may persist, fluctuate, or re-emerge after initially disappearing.
Some of the most frequently reported symptoms include:
- Severe fatigue, especially after physical or mental activity.
- Cognitive issues, often described as brain fog.
- Dizziness or lightheadedness.
- Changes in taste or smell.
Additional symptoms can include:
- Sleep disturbances.
- Shortness of breath.
- Persistent cough.
- Frequent headaches.
- Irregular or rapid heartbeats.
- Gastrointestinal problems, such as bloating, diarrhea, or constipation.
Beyond these symptoms, long COVID can exacerbate pre-existing conditions or contribute to the development of new diseases, such as:
- Heart disease.
- Autoimmune disorders.
- Chronic kidney disease.
- Migraines.
Individuals may also develop conditions directly linked to long COVID, such as:
- Mood disorders, including depression and anxiety.
- Blood clots or strokes.
- Postural Orthostatic Tachycardia Syndrome (POTS).
- Chronic Fatigue Syndrome (ME-CFS).
- Mast Cell Activation Syndrome.
- Fibromyalgia.
- Diabetes.
- Hyperlipidemia (high cholesterol).
Surprisingly, people can develop long COVID symptoms even if they were asymptomatic or had mild symptoms during the initial infection. These lingering effects may manifest weeks or even months after recovery.
It’s important to note that long COVID is not contagious. While the virus spreads between people, the long-term effects do not.
Why Does COVID-19 Cause Long-Term Health Issues?
Researchers are still working to understand why COVID-19 can lead to prolonged illness. Although the exact mechanisms aren’t fully known, several theories have been proposed:
- Immune System Dysfunction: COVID-19 may disrupt immune system communication, potentially causing immune cells to mistakenly attack the body’s own tissues. This autoimmune reaction may explain the persistent symptoms.
- Reactivation of Latent Viruses: Some scientists speculate that COVID-19 may awaken dormant viruses in the body, leading to ongoing illness.
- Gut Dysbiosis: COVID-19 could upset the delicate balance of microorganisms in the gut, affecting overall health.
- Virus Persistence: There is some evidence suggesting that the virus may survive in certain areas of the body, such as the gut, and continue to cause health problems.
- Damage to Blood Vessels: COVID-19 may damage the cells lining blood vessels, leading to cardiovascular complications.
- Nervous System Impact: The virus may interfere with communication between the brainstem or the vagus nerve, which controls many automatic bodily functions like heart rate and digestion.
Due to the constantly evolving nature of the virus, it’s difficult to estimate exactly how many people develop long COVID. However, some studies suggest that between 10% to 35% of people who contract COVID-19 experience long-term effects.
Who Is at Risk for Long COVID?
Although research is still ongoing, early findings suggest that certain groups may be more prone to developing long COVID. Some of the risk factors identified so far include:
- Gender: Women of all ages are more likely to report long COVID symptoms compared to men.
- Pre-existing Conditions: Individuals with cardiovascular diseases may have a higher risk of developing long COVID.
- Vaccination Status: Some research indicates that receiving the COVID-19 vaccine may reduce the likelihood of developing long COVID, though this is still being studied.
Many other potential risk factors are under investigation, and more insights will emerge as research progresses.
What Should You Do If You Have Long COVID Symptoms?
If you suspect you may have long COVID, it’s important to consult with a healthcare provider. Long COVID is characterized by symptoms that persist for at least three months after the initial infection.
However, diagnosing long COVID can be challenging. There is no specific test for long COVID, and many people may not have taken a COVID-19 test during their infection, especially if they were asymptomatic or had mild symptoms.
Symptoms of long COVID can be unpredictable, varying from day to day or even disappearing for a time before returning. A healthcare professional will typically rule out other conditions before diagnosing long COVID and may order tests such as blood work or imaging based on your symptoms.
Treatment and Management of Long COVID
Treating long COVID can be complex, and care plans are usually tailored to the individual’s symptoms. Some treatments may involve managing symptoms like:
- Fatigue: Your healthcare provider may recommend pacing your activities. If your symptoms worsen, it’s important to rest and avoid pushing through the tiredness.
- Pain or Breathlessness: Medications, supplements, or referrals to specialists may be suggested, depending on the severity of your symptoms.
- Brain Fog: A comprehensive treatment plan may include cognitive therapies or lifestyle adjustments to help manage memory and concentration issues.
For those experiencing a loss of taste or smell, a therapy known as olfactory training may be beneficial in retraining the nerves responsible for these senses. Additionally, individuals with POTS or abnormal heart rhythms may benefit from prescription medications and hydration plans.
Preparing for a Doctor’s Appointment
If you are experiencing long COVID symptoms and need to see a healthcare professional, preparation is key. Be ready to provide a detailed history of your symptoms, including:
- When the symptoms began.
- How frequently they occur and whether they fluctuate.
- What activities or factors seem to make them worse.
It’s also helpful to bring a list of any medications or supplements you’re taking and to ask questions about your condition and possible treatments. You may even consider bringing a trusted friend or family member to take notes during the appointment.
Challenges in Receiving Care for Long COVID
Accessing treatment for long COVID can be difficult for several reasons. People with this condition may have their symptoms dismissed by medical professionals, family members, or employers. Those facing language or cultural barriers may struggle even more to receive proper care and diagnosis.
Additionally, individuals with limited access to healthcare or financial resources may experience delays in receiving a diagnosis or treatment for long COVID.
Maintaining detailed records of your symptoms and healthcare visits can help you track your progress and communicate more effectively with your healthcare team.
How Long Can Long COVID Last?
Long COVID symptoms may improve over time, but for some, the condition can last for years. While many people gradually recover, the timeline for improvement varies widely between individuals.
Next Steps for Managing Long COVID
Managing long COVID often requires a multidisciplinary approach. As research continues to uncover more about this condition, new treatment options may become available. Until then, it’s essential to work closely with your healthcare provider to manage your symptoms and maintain your quality of life.
