Common Cold/Flu

 Common Cold and Flu are some of the most common medical illnesses. Each year, millions of people suffer from colds and flu, yet there is no effective medical treatment. Why? Because viruses causing these illnesses keep changing their chemical structure. That's why you do not acquire permanent immunity after an episode of the flu or common cold as you do with other viral illnesses, such as the Measles. For the same reason, Flu vaccines are not very effective either, although millions of Americans receive these shots every year. Majority of them end up getting the Flu anyway. The effectiveness of Flu vaccine to prevent flu has varied from 10% to 60% over the last decade. In 2015, the effectiveness was only 23% according to CDC. 

Therefore, most people stay at risk for developing flu even if you got the flu shot.

Usual Medical Treatment may Cause more Harm than Good. 

Usual Medical treatment of the Flu and Common Colds is aimed at controlling the symptoms. These treatments are readily available over the counter. It is a multi-million dollar industry. These remedies primarily consist of a nasal decongestant, an antihistamine, a cough suppressant and a pain reliever.

Each one of these ingredients can cause severe side-effects. For example, a nasal decongestant can raise blood pressure, cause rapid heart beat and may even cause a heart attack. Most antihistamines often cause drowsiness and its serious consequences, such as a car accident.They can also cause acute retention of urine and an acute episode of glaucoma. Cough suppressants really do not work except for brief periods. Pain relievers such as Acetaminophen (Tylenol in the USA) can cause liver damage. Other pain relievers, such as Ibuprofen, Naprosyn and Naproxen, can cause stomach upset and rarely, bleeding from the stomach and acute renal shut down in patients with diabetes and any cardiovascualr disease or chronic renal disease.

In addition, here is the biggest problem: These treatments often prolong the illness, leading to prolonged use of these medications which culminates in the unnecessary prescription of Antibiotics with their own potential serious side-effects.

How do these treatments prolong the illness?

You need to understand how your body responds to an attack by an army of viruses: The affected areas, such as the nose, sinuses and throat, get inflammed, which enhances blood circulation to these areas, bringing in an army of Your Immune Cells to fight off the invading viruses. As a result, there is an increased production of secretions in the nose and throat area. In addition to killing off viruses, the body also flushes away the invading viruses in these secretions.

Now, consider how a nasal decongestant works: These drugs reduce the blood flow to the nose and throat area. How does an antihistamine work? By drying up the secretions in the nose, sinuses and and throat area. Isn't it obvious that these treatments work against your immune system and helps to prolong your illness?

Another problem: For your immune system to effectively fight off viruses, it needs full support from your entire body. In order to conserve energy, the body must rest and provide as much energy to the immune system as it needs. That's why there is sneezing, watery eyes, body aches and pains, exhaustion, fever and headaches. All of these symptoms force you to take rest. However, you decide to take the medicines that temporarlly control your symptoms and you continue with your work and other activities instead of resting. Once,  the effect of theses medicines wears off, you feel worse. Then, you take the next dose and the vicious cycle continues.

A More Physiological, Safe and Effective Approach

 Here is an outline how I treat cold/flu. This approach is physiological, boosts up your own immune system and is very effective. It shortens the course of the illness and has No side-effects. 

1. Rest, which includes no reading, watching TV, surfing the internet or chit-chatting. All of these mental activities consume a lot of energy.

2. Stay warm.  

3. Local Heat Application on nose, eyes, ears and throat.

4. Frequent cleansing of nose and mouth with tolerably hot water. Steam inhalation three times a day.  

5. Drink large amounts of warm liquids.

6. Eat plenty of food if you have cold. But people with Flu often have nausea. Eat chicken-vegetable soup and other liquids. Eat plenty of fresh fruits including oranges, grapes, bananas, apples and pears. 

7. Vitamin D: Triple your daily dose of Vitamin D3 for three days. 

8. Zinc.Take Zinc as throat lozenges three times a day.

9. Vitamin C and Echenacea in tablet or liquid form.

10. You can find over-the-counter preparations containing these natural ingredients.  

In addition, Anti-flu-virus drugs againstshould be considered in persons with compromised immune system such as the elderly, children under the age of 4 and people on immunosuppressive drugs.


The Choice is Yours! 

I just shared with you my own experience and thoughts about the treatment of the Flu and Common Colds. It is not my intention to convince you one way or the other. Ultimately, the choice is all yours!

This article was written by Sarfraz Zaidi, MD, FACE. Dr. Zaidi specializes in Diabetes, Endocrinology and Metabolism.

Dr. Zaidi is a former assistant Clinical Professor of Medicine at UCLA and Director of the Jamila Diabetes and Endocrine Medical Center in Thousand Oaks, California.

Here is a case hitory of one of my diabetic patients, in his own words:

I am a 67 years old Type 2 diabetic. Here is my recent experience with an episode of cold. 

On October 8th, my 25 - year old son came down with a cold and cough, and it got worse by the next day. He wanted me to take him to a walk-in Clinic the clinic, which I did. The wait at the clinic was some two hours.  While sitting in the clinic, I started to notice cold symptoms for myself - my nose started dripping  continually. My son was given antibiotics and we returned home by 8 pm.

My regimen starting at 8 pm as follows:

1- Stopped all of the use of computer and cell phone.

2- Stopped talking. 

3- Took Vitamin D3 as 20,000 IU. 

4- Started steam inhaling with a table spoonful of Turmeric. 

5. Focused my mind that I will get over it in 24 hours. 

6- Made soup with 1/8 cup of lentils and vegetables with mustard seeds, cumin and Fenugreek seeds. 

7- Did steaming again at 10 pm before going to sleep. 

8- Also, did salt water gargle in the night and am. 

9- Ate one orange a day and ate one boiled egg a day and Mung dal pancakes with vegetables every day.

10- October 10th at 8 am, some light cough also started. I increased the frequency of steaming with Turmeric to every two hours. By 9 pm that evening, I was feeling better but not completely back to normal.

11- By October 11th at 8 am, I was pretty fine.  The cough continued for three or four days in the morning only and would go away after steaming.   I continued 20,000 IU per day of Vitamin D for 4 days and went back to 10,000 a day routine. I took blood sugar readings from the onset for four days in the mornings
and they were in the 100 to 104 range.  After four days, they are back to
my usual range of approximately 90 to 98.

Coming back to my 25 - year old son. He completed his 7 - day antibiotics course. Two weeks later, his morning cough is not completely gone. His diet was lemon chicken soup, Lentil soup and Chicken samosas for the first four days. After that he is back to his normal diet of fish, chicken and vegetables. He also did some salt water gargles and increased his vitamin D intake to 20,000 IU as well. But, he did not put his mind or body to rest. He also did not stop talking. In addition, he continued his usual judgments.

My lessons from this experience:

1- Found doing nothing and reducing the cognitive load to minimum very useful.

2- Doing away with talking seem to help as it has both a calming influence as well as add to the physical rest.

3- After bouncing back, continue to pace myself carefully.  (In general, always pace yourself and pay attention to your self.)

4- Approaching the episode with an open mind does make a difference. In other words, don't start talking to people telling them how miserable you are and so on.

5- Preserve the energy.  Suspend judgments.
