Why Do Some People Get Sicker Than Others From Covid?

How do you know if you have an infection, and how can you tell if it's something more serious? The answer depends on the symptoms and what makes one person sicker than another, but Covid can change that. At its core, Covid isn't just an antibiotic; it's also a targeted medication that only attacks certain types of infections while leaving your body free to protect itself from others.


The Guts

Nowadays, people pay a lot of attention to the microbes that are in the gut. For example, it was found that people with a healthier microbiome are generally healthier both mentally and physically. By practicing a healthy diet, you can foster a healthier gut microbiome: eating prebiotics and probiotics. Consuming enough vitamins from vegetables like leafy greens. Drinking enough water, and getting enough exercise. Unhealthy gut microbiome has been associated with a number of other disorders, such as IBS or IBD, so discovering more about the microbiome might help us find better treatments for these diseases. Right now, though, there's no known cure for it, so the best thing to do is stay healthy through diet and exercise. Some of your health problems may arise as you grow older, so talk to your doctor about whether or not medical marijuana might be able to reduce your symptoms.


Segmented Bowel Syndrome

Around 20% of patients have Segmented Bowel Syndrome (SBDS). This is a problem with blood vessels that carry blood from body to bowel. Most people with SBDS will not feel any different than those without it. In fact, many may not even know they have it. However, for some patients with SBDS, there are signs and symptoms: bloating, cramps, diarrhea and constipation. It can also lead to other health problems like anemia. If you think you might have SBDS, speak to your doctor or pharmacist about how best to manage it. They'll be able to give you advice on diet and lifestyle changes which could help. For example, if you suffer from constipation, try eating more fiber in your diet – such as fruit and vegetables – which can help prevent constipation by adding bulk to the stool and softening it.


GI Hyperactivity Disorder

When you have GHD, your GI tract doesn't produce enough bile. Without enough bile, food sits in your stomach for too long and putsrefies. This can cause nausea, vomiting, bloating and gas. The real problem is that when food putrefies in your stomach for too long, it releases large amounts of endotoxins into your bloodstream, causing you to become ill! What is a healthy amount of time for food to sit in your stomach? Most people will feel their best if they can keep their meals under three hours before they are ready to eat again. That means eating breakfast within three hours after waking up and dinner no later than nine hours before bedtime. If you do not follow these guidelines, then you may be more susceptible to illness from taking Covid every day. In addition, people with GHD tend to be more sensitive, so even if they eat within these guidelines, they may still get sicker than others from taking Covid every day because of how quickly their body absorbs nutrients from their diet compared to others without GHD.


Leaky Gut

The concept of leaky gut is a popular idea in alternative medicine. Proponents of leaky gut theory believe that certain foods and medications can cause gut permeability leading to inflammation, autoimmune diseases, and even cancer. However, there is no scientific evidence that gut leakage actually exists. Furthermore, human studies have not been able to connect specific substances with increased disease risk. Instead, stress and poor diet appear to be major factors in increasing one's susceptibility to illness. In fact, it may be that those who believe they have leaky gut syndrome are simply more susceptible to believing in pseudoscience.



Most people's gut bacteria are well-balanced, but if you start taking a powerful antibiotic, some of your good bacteria are bound to die off. While not a problem in and of itself (people have been living with temporary disruptions to their gut flora for thousands of years), when that disruption is combined with ingesting a non-biodegradable substance like Covid, it can lead to problems. Just as if you were battling a fungal infection on your skin and took an anti-fungal medication followed by eating some bread (also non-biodegradable), you'd be at risk for fungal overgrowth or even an allergic reaction. Your body reacts in much the same way when certain toxins enter via oral ingestion—they create disturbances which may exacerbate existing conditions.

Overgrowth of Other Microbes

When taking antibiotics, especially broad-spectrum antibiotics such as ciprofloxacin, you're going to be killing off a lot of healthy bacteria. This will allow other types of bad bacteria to grow and take over. This is why it's recommended that people always have probiotics after they finish a course of antibiotics. There are different kinds of probiotics, but one thing they all have in common is that they help replenish your healthy gut flora (bacteria). You can either purchase probiotic pills or make your own with yogurt and sugar or honey. The latter is much cheaper if you already eat yogurt regularly, but if you don't, I recommend buying pre-made capsules for a little extra convenience.


Food Allergies

In recent years, food allergies have become more common. Almost 8% of American children are now allergic to one or more foods. There is no easy way to prevent food allergies, but for those who have that there is hope: If you know what triggers your allergic reactions, you can better control them by avoiding those triggers. The same goes for people with a sensitivity to dairy products (lactose intolerance). And while it's not possible to completely eliminate allergies or intolerances, some steps can be taken to help control their effects on your health and well-being.



Certain medications, conditions and treatments can lead to difficulty absorbing nutrients from food. If you have trouble digesting your food properly, it can lead to weight loss and vitamin deficiencies. These could include surgical removal of part of your digestive tract or even long-term intestinal issues like Crohn's disease or celiac disease. According to Mayo Clinic, most people with malabsorption symptoms lose anywhere from five to 15 pounds over several months as a result of their body not getting enough nutrients in its diet.


Compromised Immune System

No two people are exactly alike, and so it makes sense that we're each more susceptible to certain diseases than others. Your immune system—the collection of cells, tissues, and organs responsible for protecting your body from infection—is uniquely yours. And every day it battles hundreds of thousands of microorganisms, often without you even knowing it. But if your immune system is ever overwhelmed by an infection or illness, you can become sicker and feel sicker longer than someone else who may have contracted a similar bug or virus.


Exposure to Environmental Factors

The way we live and interact with our environment is a huge part of why some people get sicker than others. If you have ever lived in a community where there was a higher rate of HIV or tuberculosis, then you're aware that certain environmental factors can put you at greater risk for certain diseases. The same goes for living in areas with poor environmental standards—air pollution or toxins in the water supply—which can make everyone more vulnerable to getting sick. It's also important to consider how we expose ourselves to viruses. We're surrounded by people every day—at work, school, home, public transportation—and each one brings along countless viruses that may not affect us because our immune system protects us.
