Nutrition at 64: Bone Scans, Vaccines and Grip Tests

Sixty-four is a good year for a full audit, because several things change at 65 and a baseline makes them interpretable. Bone density, grip strength, a medication review, vaccination status and the standard bloods between them cover almost everything that is both common and actionable — and most of this list is never offered unless you ask.

The bloods

The kidney function line matters more than it looks. Protein recommendations for older adults are higher than the general adult RDA, and the main caveat is kidney disease. Knowing your eGFR means you can follow the higher targets in nutrition at 65 with confidence rather than avoiding protein out of the myth addressed in nutrition at 60.

The scans and the functional tests

A DEXA scan at 64 is the one most worth pushing for, particularly for women, because it converts a vague worry into a number you can track. Bone loss after menopause runs fastest in the first five to seven years, as nutrition at 48 describes, so by 64 a good deal has already happened and it helps to know how much.

The functional tests are free and nobody does them. Grip strength and chair-stand time are the same measures used clinically to identify sarcopenia, and having your own numbers at 64 makes a reading at 74 meaningful rather than abstract.

The medication review

Prescriptions accumulate across decades and are rarely subtracted. By the mid-sixties many people take five or more regular medicines, and each was started for a good reason that may or may not still apply.

• Ask whether every medicine is still needed, and what would happen if one stopped.
• Ask specifically about anything sedating, and anything that lowers blood pressure on standing — both raise fall risk.
• Ask about nutrient interactions: metformin and B12, PPIs and B12, iron and calcium, levothyroxine timing, as nutrition at 55 covers.
• Ask whether any iron supplement is still appropriate, particularly for post-menopausal women.
• Bring every box, including anything bought over the counter and any ayurvedic or herbal preparation.

That last point matters more than people expect. Herbal and over-the-counter products are frequently not mentioned because they are not thought of as medicine, and several interact meaningfully with prescription drugs.

Vaccination, which is rarely raised

Adult vaccination is poorly covered in India and almost never discussed unless the patient asks. The ones generally worth discussing around this age are influenza, pneumococcal and herpes zoster, with tetanus boosters and hepatitis B depending on history.

Whether each is appropriate depends on your health, conditions and local availability, so this is a conversation rather than a checklist to act on alone. The point is simply that it is a conversation most people never have.

What to change, in order

Resistance training is first for the same reason it is first at 39: it moves more measures simultaneously than anything else — muscle mass, bone density, insulin sensitivity, grip strength, balance and blood pressure. At 64 it also directly reduces fall risk, which is the mechanism by which most later harm arrives.

Nutrition at 65 picks up with frailty and fall prevention, and nutrition at 39 is the same audit done twenty-five years earlier.

Where KABO fits in

This page is a list of tests and questions. Almost none of it involves buying anything, and the single highest-return item on it — resistance training twice a week — is free.

The one dietary item is protein at 1.0–1.2 g/kg with roughly 30 g a meal, which most Indian vegetarian diets miss by a wide margin, mostly at breakfast. A KABO serving provides 23–25 g of complete plant protein with 26 vitamins and minerals. Get your eGFR checked first, as the page says, so you know the higher protein target applies to you.

Frequently asked questions

What health checks should I get at 64?

A full blood count with ferritin, B12 and folate; HbA1c; a lipid profile; creatinine with eGFR; TSH; vitamin D and calcium; and liver function. Alongside those, a DEXA bone density scan, grip strength, a timed chair stand, a dilated eye exam, a hearing test and a dental review.

Should I get a bone density scan at 64?

It is worth asking for, particularly for women, because bone loss runs fastest in the first five to seven years after menopause and a good deal has already happened by 64. A DEXA scan converts a vague worry into a number you can track, and it is rarely offered in India unless requested.

Why does kidney function matter for protein?

Because protein recommendations for older adults are higher than the general adult RDA, and the main caveat is kidney disease. Knowing your eGFR lets you follow the higher targets with confidence rather than avoiding protein on the basis of the myth that it harms healthy kidneys.

What should I ask in a medication review?

Whether each medicine is still needed, what would happen if one stopped, which are sedating or lower blood pressure on standing, and which have nutrient interactions such as metformin or PPIs with B12. Bring every box, including over-the-counter, ayurvedic and herbal products.

Which vaccines are recommended at 64 in India?

Influenza, pneumococcal and herpes zoster are generally worth discussing around this age, with tetanus boosters and hepatitis B depending on history. Adult vaccination is poorly covered in India and rarely raised unless the patient asks, so it is worth bringing up yourself.
