Introduction

Every year on 12 December, the world celebrates Universal Health Coverage Day — a commitment that everyone should have access to healthcare that is affordable, safe, and effective.

But as medical knowledge advances, one question becomes clear:

Is healthcare truly “universal” if treatments work well for some people, but not for others?

Today, we know that:

• Some people respond well to a medicine
• Some get severe side effects
• Some need higher doses
• Some need lower doses
• Some need a completely different treatment

Not because their condition is different —
but because their genetics are different.

Universal Health Coverage cannot stop at “everyone gets access.”
It must evolve into:
“everyone gets the care that works for them.”

This is where PGx (pharmacogenomics) and NGx (nutrigenomics) reshape the meaning of universal care.

1. What Does Universal Health Coverage Actually Mean Today?

UHC is built on three promises:

✔ Accessible care — everyone can receive treatment

✔ Affordable care — treatment does not cause financial hardship

✔ Effective care — treatment actually works for the patient

The first two are widely discussed.
The third — effectiveness — is often assumed.

But in reality:

• One medication may work for 70% of people
• 20% get mild side effects
• 10% get severe side effects or no improvement

If your body cannot metabolise the drug properly, even the best healthcare system cannot guarantee effectiveness.

This gap is where personalised medicine shines.

2. PGx Ensures That Medication Is Safe and Effective for Each Person

Pharmacogenomics helps identify:

✔ Who needs a lower dose

✔ Who needs a higher dose

✔ Who should avoid a certain drug

✔ Who may get more side effects

✔ Who may not respond at all

This matters for many common medications:

• Statins
• Antidepressants
• Antiplatelets
• Painkillers
• Blood pressure medications
• Gastric medicines
• Anti-epileptics
• Diabetes medications

Without PGx, healthcare professionals often rely on:

• Trial and error
• Waiting for side effects
• Adjusting repeatedly
• Guessing the “best” dose

With PGx, they rely on:
data, safety, precision, and personalised dosing.

This is not luxury medicine —
This is safer medicine.

3. Why PGx Belongs in Universal Health Coverage

Because medication errors and poor response cost:

• Time
• Money
• Emotional stress
• Hospital visits
• Additional medications
• Loss of trust in treatment

PGx supports UHC by:

✔ Reducing unnecessary medicine switches

✔ Reducing dangerous side effects

✔ Reducing hospital admissions

✔ Improving treatment success

✔ Saving system-wide healthcare costs

✔ Protecting vulnerable groups

(elderly, polypharmacy, chronic patients)

A universal system should prevent problems, not respond after they happen.

4. NGx (Nutrigenomics) Helps Prevent Future Illness

Universal care isn’t only about treatment —
it is about prevention, quality of life, and long-term health.

NGx helps reveal:

• Vitamin D activation issues
• Omega-3 EPA conversion
• Magnesium absorption
• Folate pathways
• Sweet/bitter sensitivity
• Inflammation tendencies
• Appetite and metabolism traits

This helps Malaysians personalise their wellness approach:

• More energy
• Better mood
• Better metabolic balance
• Reduced inflammation
• Better digestion
• Healthier long-term disease prevention

NGx reduces future burden on the healthcare system —
which is a core purpose of Universal Health Coverage.

5. UHC in Malaysia: A Multi-Ethnic Population Needs Personalised Care

Malaysia’s strength is diversity —
but diversity means genetic variation.

Across Malay, Chinese, Indian, Indigenous, and mixed communities, we see unique patterns in:

• CYP2C19 metabolism
• Statin sensitivity (SLCO1B1)
• Carbamazepine safety (HLA-B*1502)
• Vitamin D activation
• Omega-3 metabolism
• COMT stress sensitivity

A standard guideline cannot fit every Malaysian body equally.
Real universal care must recognise variations, not ignore them.

6. PGx + NGx Helps the Healthcare System Allocate Resources Better

Personalised medicine helps at national levels by:

✔ Reducing wasted treatment

✔ Lowering total medication costs

✔ Cutting down trial-and-error cycles

✔ Reducing emergency visits

✔ Allowing doctors to make faster decisions

✔ Improving chronic disease control

UHC becomes stronger when healthcare becomes more precise.

7. Case Example (Anonymised)

A 52-year-old man struggled with:

• Statin muscle pain
• High cholesterol despite medication
• Low energy
• Sleep difficulty

PGx result:

• SLCO1B1 decreased function → high risk of statin-related muscle injury

NGx result:

• Low Omega-3 EPA conversion
• Vitamin D activation issues

His doctor adjusted his medication, and his pharmacist personalised a nutrition plan.

Results after 2 months:

• Less muscle pain
• Improved lipid profile
• Better sleep
• Stabilised energy
• Improved confidence in treatment

This is what effective universal care looks like —
care that adapts to the individual.

Conclusion

Universal Health Coverage means everyone deserves access,
but personalised medicine means everyone deserves effectiveness.

Healthcare cannot be truly universal if:

• Some people receive medication that doesn’t work
• Some people face unnecessary side effects
• Some people struggle for months trying to find the right treatment
• Some bodies react differently but are treated the same

The future of UHC is clear:

Equal access + personalised precision = real universal healthcare.

This is how we respect every Malaysian’s biology, dignity, and right to safe treatment.
