How to know if I am at high risk to COVID-19 disease?

How do I know if I have low immunity?

As explained & established in the last lesson “Lesson 6 – Which people are at high risk to COVID-19 infection?“, only those people that have low immunity are at high risk to getting COVID-19.

Therefore, the question “How to know if I am at high risk to a COVID-19 infection?”, ought to be re-framed to “How do I know if I have low immunity?”. Doing so can help you get a specific & objective answer and then lead you to seek out the most efficient ways to normalise & continuously optimise your immunity.

Below are a the ways by which you can speculate with high probability whether you have low immunity or not.

Health conditions & lifestyle patterns that certainly result in lowered immunity:

(and thereby into a high risk to COVID-19 infection):

If you have any one or more of the following conditions or lifestyle patterns, the probability that you have low immunity certainly high.

  1. You have any chronic disease (example: Cancer, Heart disease, Stroke, Diabetes, Kidney disease, Liver disease, Digestive diseases, Autoimmune diseases, Cardiovascular diseases like high blood pressure, Respiratory diseases, Joint & muscle & skeletal diseases, Reproductive diseases, Women specific disease, Skin diseases, etc.)

  2. You consume medications, or undergone degenerative therapies such as Chemotherapy, Radiation, etc.

  3. You have visceral fat & obesity

  4. You have a highly acidic diet (diet high in starch, sugar and artificial additives)

  5. You smoke cigarettes

  6. You consume alcohol regularly

  7. You are over-exposed to a polluted environment, EMF radiation, and non-hygienic conditions.

  8. You have chronic mental & emotional negativity (chronic thoughts & emotions of fear, anxiety, worry, stress, depression, anger etc.)

  9. You have internal toxicity (toxins & heavy metals in your body)

  10. You have a lack of essential nutrients

  11. You have a sedentary lifestyle (lack adequate movement & exercise)

  12. You have a lack of appropriate rest

Signs & Symptoms of low immunity:

(and thereby signs & symptoms of high risk to COVID-19 disease):

Here are some symptoms of low immunity; if you have any one or more of these, the probability of you having low immunity is high:

  • Lack of energy, chronic fatigue & easily tired

Medical tests for confirmation of low immunity:

 (and thereby for confirmation of high risk to COVID-19 disease):

While there are no specific tests to certify the condition of your immunity specifically against COVID-19 infection, there are many advanced tests that can be used together in an integrated & holistic approach to determine the overall state of immunity and the overall condition of health. Here are some of such tests:

  • Medical history analysis
  • Digital meridian scan
  • Live blood analysis
  • Dry blood analysis
  • Blood chemistry analysis
  • Nutritional status test
  • Hormonal profile test
  • Toxicology test
  • Free radical test
  • Urine test

What can we offer you in Heal Within™

Heal Within™ is primarily a chronic disease treatment & prevention centre, based on an Integrated & Holistic treatment protocol. Our focus and relentless pursuit is to help chronic disease patients achieve these Three Primary Objectives.

  • Objective 1: Holistic Healing
  • Objective 2: Optimal Immunity & Disease-Occurence/Recurrence Prevention
  • Objective 3: Long-term Wellbeing

To learn the details of the what & why of these end-objectives, and understand why it is crucial that you establish this in your mind first prior to starting any healthcare treatment or prevention program, please go to Lesson 1 – First, Establish Your End-Objectives (if you not already done so).

We use an advanced Integrated & Holistic Treatment approach, by which we diagnose the root causes to the patient’s diseases by specialised tests in all 10 Pillars of Health, and then treat those specific root causes by specialised therapies that induce holistic healing and not just suppress symptoms as done in main-stream medical treatments.

By this protocol, we have consistently helped numerous patients with all forms of diseases (right from Cancer, Heart disease, Stroke, Kidney disease, etc. to High blood pressure, diabetes, skin diseases, auto-immune diseases, infertility & other women issues, obesity etc.;) achieve these Three Primary Objectives.

If you have any chronic disease and not getting the desired positive results from your present treatment, or if you want to optimise your health to prevent occurrences of any chronic disease, or if you want to optimise your immunity for optimal prevention against COVID-19, then just send us an enquiry or come visit our centre and see how we can help you achieve the Three Primary Objectives.

We have both: a comprehensive service in-clinic program, and a DIY-at-home program (i.e. do it yourself at home program).

Our offerings:

  • Education: How to Prevent & Treat of Chronic Diseases (including COVID-19)
  • Diagnosis: Comprehensive health screening for Diseases & their Root Causes (including COVID-19)
  • Prevention: Chronic Disease Prevention Programs (including COVID-19)
  • Treatment: Chronic Disease Treatment Programs
  • Rehabilitation: Post-treatment Rehabilitation & Optimisation Programs (including COVID-19)
