I'm a Doctor and These COVID Symptoms Alarm Me

Although COVID cases are declining and the surge is pretty much over, the virus is still very present and causing serious long-term effects for millions of people. Even for people who have experienced a mild case of COVID, they are at risk for severe health issues like heart damage, according to Dr. William Haseltine, a scientist who has worked on the forefront of medical research with cancer and AIDS, an internationally recognized expert on COVID, Harvard professor and author who spoke with Eat This, Not That! Health. Read below to find out the symptoms that are causing lifelong problems and what Dr. Haseltine believes people should know about the virus–and to ensure your health and the health of others, don't miss these Sure Signs You've Already Had COVID.


Why Do Some People Experience COVID More Severely Than Others?

Dr. Haseltine explains, "The answer has to do with either their age or underlying health conditions. The older you are the more likely you are to suffer serious consequences. The reason for that is because the older you are the weaker your immune system, both your innate and adaptive immune system. Then, there are also predisposing conditions – any immunological disorder, cancer treatments, morbid obesity, diabetes, and obstructive pulmonary disorders and a few others but those are the main ones."


How Long Do Lingering Symptoms Last?

Dr. Haseltine says, "They have lasted as long as we can measure them now from the very first people that contracted COVID. There are some people who have lingering symptoms for more than three years, and there is some permanent damage that can be done to several critical systems, particularly the heart."


Brain Fog and Fatigue

According to Dr. Haseltine, "Some other people experience some very long-term brain fog, or mental dysfunction, that is sometimes so serious that they can't work. The most common long-term symptom is fatigue, and in some cases, the fatigue is so serious that they can't work.  The overall phenomenon we call Long COVID or post-acute PASC."


Serious Heart Disease

"SARS-CoV-2 infections can damage heart muscle and affect heart function," says Dr. Haseltine. "There are several reasons for this. The cells in the heart have angiotensin-converting enzyme-2 (ACE-2) receptors where the coronavirus attaches before entering cells. Heart damage can also be due to high levels of inflammation circulating in the body. As the body's immune system fights off the virus, the inflammatory process can damage some healthy tissues, including the heart. SARS-CoV-2 infection can also affect the inner surfaces of veins and arteries, which can cause blood vessel inflammation, damage to very small vessels, and blood clots, all of which can compromise blood flow to the heart or other parts of the body."


Millions of Americans Are Expected to Have Serious Heart Issues Due to COVID

Dr. Haseltine reveals that the, "Most recent data from the US Department of Veterans Affairs on a very large number of people suggests that the serious cardiac symptoms affect 45 people out of 1,000 for a year or more, regardless of age, vaccination status and severity of disease when they caught it. Because there are estimates now of 140 million Americans, that means there are something like 6.3 million Americans are likely to have right now serious heart conditions for over a year. It is going to be a major problem for our health system and for people. And when I talk about major heart conditions, I mean heart attacks and other serious issues."

"SARS-CoV-2 infections may raise the risk of developing diabetes, because the virus can damage insulin-producing cells in the pancreas," states Dr. Haseltine. 

Harvard Health reports, "Experts have found that the virus that causes COVID-19 can directly attack insulin-producing structures in the pancreas. According to the NIH director's blog, researchers found that the virus, called SARS-CoV-2, affects the pancreas in three different ways. First, it may directly damage pancreatic beta cells, the ones that produce insulin, reducing their ability to make enough insulin to keep blood sugars controlled. Second, as the virus replicates in the pancreas, it also can damage the cells that directly surround the beta cells, which are needed for proper insulin release. Third, the virus also seems to reprogram surviving cells, making them malfunction, which can wreak havoc with blood sugar regulation."

What People Should Know

Dr. Haseltine explains, "For advice, I think health care systems should do a serious cardiac work up on all patients that have been infected by COVID. Patients should be aware that having COVID, even if it was the mildest of cases, puts them at equal risk for serious heart disease to someone that was in the ICU. It is a risk of about 5% of people, who have had any form of COVID, regardless of vaccination status. It's really confounding. People can't understand how all of this damage can occur to the heart if you've been vaccinated or had even a mild case. Long COVID is a very serious long-term consequence of this disease."

Follow the public health fundamentals and help end this pandemic, no matter where you live—get vaccinated or boosted ASAP; if you live in an area with low vaccination rates, wear an N95 face mask, don't travel, social distance, avoid large crowds, don't go indoors with people you're not sheltering with (especially in bars), practice good hand hygiene, and to protect your life and the lives of others, don't visit any of these 35 Places You're Most Likely to Catch COVID.

When Should I Take Creatine?

Creatine is probably the most well-researched supplement on the market today. Numerous studies have found positive adaptations in strength, power and muscle mass thanks to creatine supplementation—especially when it's combined with resistance training. Although the benefits of creatine are well-known to lifters, the best time to take it isn't common knowledge. Which leads us to some important questions:     Does an optimal time for consuming creatine exist?     If it does, should you take it before or after your workout? According to a new study published in the Journal of Exercise and Nutrition, the timing of creatine ingestion does indeed play a role in getting bigger and stronger. Creatine supplementation before resistance training increases muscular strength and lean muscle mass. Interestingly, taking creatine immediately after lifting weights results in greater muscle growth than taking it immediately before. However, in terms of strength gains, no difference betw

Best Smoothie Habits for Weight Loss, According to Dietitians

When it comes to trying to lose weight , most of us are rather poor math students. We mess up the addition and subtraction all the time. We'll try to subtract calories by skipping meals only to become ravenous later on and undercalculate how much food we've eaten to satisfy that gnawing hunger .
