Dr. Johnston explains, "While most people who get infected with COVID recover fully and fairly quickly, some patients experience a whole host of various symptoms that can last months to longer. This can happen to patients not only with severe COVID but those who had minimal to little symptoms during their acute illness."

According to Dr. Johnston, "Acute COVID is known for affecting the lungs but can also have an effect on multiple systems of the body including the heart, brain, and kidneys. COVID is also associated with an increased risk of blood clotting which can lead to stroke and heart attacks, but smaller clots can have an effect on organ function in general."

Who is at Risk for Long COVID?


"Those with more severe cases of COVID tend to have symptoms that can linger for a long time, especially those that were hospitalized or spent significant time in the ICU," Dr. Johnston says. "However, even those with mild symptoms can get long COVID.  Much is still yet to be known and research is underway to determine who may be at greater risk, how to avoid long COVID, and how to treat it."

According to Dr. Johnston, "While most symptoms of long COVID do seem to improve slowly over time, some patients report persistent shortness of breath, fatigue, and mental issues. Make sure to get your rest, eat well, continue to take vitamins that support your immune system, such as vitamin C, D, and zinc, and start an exercise program slowly with guidance of your doctor to build back your endurance."

Dr. Johnston explains, "Talk to your doctor if you don't feel you are recovering normally. Additional testing may be needed to rule out damage to the heart, lungs, kidneys etc. While there isn't a specific treatment for long COVID, often addressing each system can improve symptoms. This may require a multi-physician approach. Our philosophy at Redirect Health is to have your primary care physician act as your quarterback through the process as it can be confusing and frustrating."
