Conventional medical care

Conventional medical and health care are also called allopathic or Western medicine. This is in contrast with complementary, alternative, or integrative health approaches. Most of the healthcare you have probably gotten in the United States is this type of care – the kind where doctors, nurses and other affiliated medical professionals provide the care.

This type of care generally concerns itself with diagnosing, preventing and treating disease. Disease or illness in this system of care is thought to happen because of organic changes in the body, like atherosclerosis, or from exposure to pathogens like bacteria and viruses.

The people who provide conventional care are medical doctors who hold MD or DO degrees, nurses (who may have a bachelor’s or master’s degree and who are licensed as RNs or NPs), physical therapists, and various other allied medical professionals. Examples include emergency medical technicians (EMTs), respiratory therapists, dentists, podiatrists, optometrists, and others.

Most medical doctors hold the MD (medical doctor) degree, and some may also have a DO or Doctor of Osteopathy degree. They attend accredited medical schools for several years, then have periods of residency and internship, and some may choose to specialize further. Doctors who provide general every-day medical care are usually those who studied internal medicine or family medicine. They may be known as general practitioners or primary care providers. They can see people for common complaints like respiratory infections, and well-care (check-ups that may include blood laboratories, blood pressure screenings, vaccines, and other prevention and routine care). They can order screening tests, blood work, medical imaging like X-rays or MRIs, and other diagnostic tools, and can prescribe medications. Doctors’ offices may also have Nurse Practitioners (NP) or Physician Assistants (PA) provide this kind of care under the supervision of the doctor.

Doctors who choose to specialize, spend several more years working in a particular area of medicine. This can be based on a particular body system, like cardiology or neurology, a kind of patient, like pediatrics or gynecology/obstetrics, or particular type of disease, like oncology (specializing in cancers). Usually, a primary care provider may refer their patient to a specialist if they require more than routine every-day care.

Conventional care is also found in hospitals, urgent care centers, and rehabilitation centers. Here, many allied health professionals may be present to help doctors provide care.

When should you seek emergency care and when should you go to an urgent care center? Generally, you should go to the emergency room for a life-threatening condition (heart attack), sudden serious changes like shortness of breath, numbness or paralysis, or serious/severe conditions like trauma, severe cuts or burns, severe allergic reactions and so on. Urgent care is for times when you need care right away and may not be able to see your primary provider quickly – things like respiratory infections, earaches, etc. Get your preventative care from your primary care provider.

Image that shows when to visit an emergency room and when to visit urgent care. For emergency room: major allergic reaction, broken bone, chest pain, difficulty breathing, back/neck/head injury, moderate to severe burns, vomiting, suicidal or homicidal feelings, possible drug overdose. For urgent care: cuts that need stitches, accidents and falls, fever or flu, pink eye, sore throat, sprains and strains, skin rashes and infections, moderate back pain, animal or insect bites.
Look for emergency rooms and urgent care centers that accept your insurance and are close to you.

Medicines and drugs

A drug is a substance that causes changes in the chemical and biological processes in the body. This is a very general term, and thus, drugs can fit into several categories, both beneficial and harmful to human health.

Medicine is defined as a drug that is meant to prevent, diagnose, or treat a disease. Each country defines for itself how medicines are regulated. In the United States, the Food and Drug Administration (FDA) is responsible for regulating medications.

Some medications require prescriptions from a doctor or other healthcare professional. Others are sold to anyone from a pharmacy – https://www.fda.gov/drugs/questions-answers/prescription-drugs-and-over-counter-otc-drugs-questions-and-answers. In either case, it is important to become educated about using medications safely – know about the right indication for use, the right dosage (how much active ingredient), which active ingredients are present, the risks and benefits, and possible side effects. Read more here about being an active member of your healthcare team – https://iffgd.org/manage-your-health/diet-and-treatments/medications/safer-medicine/

The active ingredient of the medication is the one that interacts with your body so as to treat a symptom or cause of a disease, or prevent or diagnose the disease. The main effect of the drug is this specific therapeutic effect. But most drugs come with side effects – effects that are beyond that main effect. These can be mild or severe. Be sure to read the label, drug package or pharmacy print-out to know what to expect.

Medications can also be brand-name or generic. Generic medications are those have been developed once the active ingredient is no longer protected by a patent. This generally means that generic medications are cheaper than the brand name alternatives. https://www.fda.gov/drugs/questions-answers/generic-drugs-questions-answers

Drugs can have interactions with other drugs, with dietary supplements, and even with food. These can amplify the main effects or side effects, cancel each other out, or cause unwanted effects. They can also change how the drug is absorbed, metabolized (or broken down) and excreted out of the body. Read more here – https://www.health.harvard.edu/staying-healthy/7-things-you-can-do-to-avoid-drug-interactions. It is important to tell the doctor or pharmacist what medications (whether over the counter, or even herbal) you use regularly, to avoid interactions.

Drug are administered into the body in several ways, including orally, through injection, by inhalation and other means. https://www.merckmanuals.com/home/drugs/administration-and-kinetics-of-drugs/drug-administration

It is possible to abuse over-the-counter and prescription medications. People may also misuse these types of medications, which means using them for a purpose other than the main effect, or using someone else’s medicines.

The immune system, infectious illness, and COVID-19

The immune system is a complex system of tissues, cells, and organs that detects and acts against threats to your health.

The first layer of protection we have against infections is our skin – it provides a physical barrier between your organs and systems and bacteria, viruses, parasites and toxins you may encounter. We also have complex microbiomes – microorganisms that exist on our skin, in our mouths and noses, and in our guts. The microbiome can protect us from certain illnesses. Finally, there are cells generated by the immune system (white blood cells like T-cells, B-cells, macrophages and others) and proteins (antibodies, cytokines and others).

Can you boost your immune system? Because it is quite complex, scientists are still unraveling all of the connections between our lifestyles and immune function. We do know there are certain behaviors that can help protect us from disease – avoiding exposures to chemicals like tobacco smoke, washing our hands, and others – https://www.health.harvard.edu/staying-healthy/how-to-boost-your-immune-system.

Microorganisms that can make us sick are called pathogens – https://www.mayoclinic.org/diseases-conditions/infectious-diseases/in-depth/germs/art-20045289. Sometimes they live on and in our bodies without causing illness. Other times, they can multiply to the levels of causing disease.

This video provides a short overview of coronaviruses.

SARS-CoV-2 is the virus that can cause COVID-19, the respiratory illness that is now pandemic. This is a novel virus, but it is related to other coronaviruses that sometimes cause seasonal colds, and have caused 2 other epidemics in the last two decades -SARS and MERS. Viruses are pieces of genetic material encased in a shell with binding proteins. They enter the body and invade our own cells in order to make copies of themselves. The above video gives a short explanation of how the coronavirus functions.

The COVID-19 pandemic began at the end of 2019. It is a respiratory disease that has a relatively long incubation period (the period of time people don’t have symptoms even if they are infected), can spread even when people don’t have symptoms, seems to mainly spread through droplet and direct contact exposure, and can cause severe illness and death in some people. Find more detailed information here – https://www.cdc.gov/coronavirus/2019-nCoV/index.html

More information on SARS-CoV-2 variants is explained here:

Late in 2020, several vaccines for SARS-CoV-2 have been developed and 3 have been approved for use in the United States (with several others being used in other countries). Vaccines generally work by teaching your immune system to create antibodies which can attack the pathogen when you come in contact with it. There are three vaccines that have been approved by the FDA.

In 2024, vaccines have been approved for most age groups, we have had booster shots, wide-spread testing became possible, and treatments for COVID-19 have improved a lot. However, variants have continued to spread and have become more contagious and mitigation policies have mostly disappeared. We’ve understood the disease more and people continue to get sick and even die, but people and governments have mostly returned back to the lives we led before the pandemic started. People can still be more vulnerable to the disease, especially those who are immuno-compromised in some way, people who are getting treated for cancer, people living with chronic diseases, and others. An important issue for all is that a considerable percentage of people who get sick with COVID-19 can develop long-term symptoms (some call this Long Covid), some debilitating. It is unfortunate that mitigation measures are no longer required and this disease is establishing itself as something we will continue to struggle with for years to come.
