Q: What is sarcopenia?

Sarcopenia is the progressive loss of skeletal muscle mass, strength, and function with ageing. It affects roughly 10–40% of adults over 65 and up to 50% of those over 80. Sarcopenia raises risk of falls, fractures, frailty, hospitalisation, loss of independence, and mortality. Unlike simple ageing, sarcopenia is partly preventable and treatable through resistance exercise, adequate protein intake, and management of underlying conditions.

Q: What is the SARC-F questionnaire?

SARC-F is a validated 5-item screening tool for sarcopenia: Strength (difficulty lifting 5 kg), Assistance with walking, Rise from a chair, Climb stairs, and Falls. Each item scores 0 (none), 1 (some), or 2 (a lot/unable). Total score ranges 0–10. A score ≥4 is considered SARC-F positive and warrants further clinical assessment with grip strength, gait speed, and body composition measurement per EWGSOP2 guidelines.

Q: What does a SARC-F score of 4 or higher mean?

A SARC-F score ≥4 indicates high screening risk for sarcopenia with roughly 60–80% sensitivity in community-dwelling older adults. It does not diagnose sarcopenia alone—you need confirmatory tests: hand-grip strength (<27 kg men / <16 kg women), gait speed (<0.8 m/s), and low appendicular lean mass on DXA or BIA. A positive SARC-F should prompt a doctor or physiotherapist visit for comprehensive muscle assessment.

Q: Can sarcopenia be reversed or prevented?

Yes—muscle loss is not inevitable. Progressive resistance training 2–3 times per week can increase muscle mass and strength even in adults over 80. Adequate protein (≥1.0–1.2 g/kg daily, with 25–30 g per meal) combined with exercise is the most effective strategy. Vitamin D optimisation, fall prevention, and treating underlying illness also help. Studies show 12–24 weeks of structured resistance training can meaningfully improve muscle function in older adults.

Q: How much protein do I need to prevent sarcopenia?

General adults need ~0.8 g/kg protein daily, but older adults (65+) need ≥1.0–1.2 g/kg—and up to 1.5 g/kg with resistance training—due to anabolic resistance. Distribute protein across meals (≥25 g per meal) with leucine-rich sources: dal, eggs, paneer, fish, chicken, Greek yogurt, and soy. Use our Protein Target Calculator for a personalised daily goal based on your weight and activity.

Q: What exercises are best for sarcopenia?

Resistance training is the cornerstone: squats, lunges, wall push-ups, resistance bands, and weight machines targeting legs, hips, back, chest, and arms 2–3 times per week. Balance exercises (tai chi, single-leg stands) reduce fall risk. Moderate aerobic activity (150 min/week brisk walking) supports cardiovascular health but does not replace resistance work. Start with bodyweight exercises and progress gradually—supervised physiotherapy is recommended if SARC-F positive.

Q: What tests confirm sarcopenia diagnosis?

EWGSOP2 defines sarcopenia in three stages: (1) Low muscle strength (grip <27 kg men / <16 kg women), (2) Low muscle quantity (appendicular lean mass by DXA or BIA below sex-specific cutoffs), (3) Severe sarcopenia when both strength and mass are low with poor physical performance (gait speed <0.8 m/s or low Short Physical Performance Battery score). Blood tests include vitamin D, CBC, thyroid, and inflammatory markers to rule out secondary causes.

Q: Who is at highest risk for sarcopenia?

Highest risk groups: adults ≥75, sedentary individuals, those with low protein intake, diabetes, COPD, heart failure, chronic kidney disease, cancer cachexia, prolonged hospitalisation, and anyone with unintentional weight loss. Post-menopausal women lose muscle faster due to declining estrogen. Indian vegetarian diets often provide insufficient protein for muscle maintenance—making nutrition assessment especially important.

Q: Is sarcopenia the same as frailty?

No, but they overlap. Sarcopenia specifically refers to loss of muscle mass, strength, and function. Frailty is a broader syndrome of decreased physiological reserve across multiple systems (weakness, slow walking, low activity, exhaustion, weight loss). Sarcopenia is a major component of physical frailty. Both increase fall and hospitalisation risk, and both respond to exercise and nutrition interventions.

Question 1

How does the Sarcopenia Risk Calculator work?

Accepted Answer

Enter your age, sex, height (cm or ft/in), and weight (kg or lb). Complete the validated SARC-F questionnaire (5 items scoring 0–2 each, max 10): difficulty lifting or carrying about 4.5 kg (10 lb), walking across a room, getting up from a chair or bed, climbing a flight of stairs, and number of falls in the last 12 months. Optionally add calf circumference (cm), handgrip strength (kg), and time to walk 4 metres (seconds). We calculate your SARC-F score (≥4 = positive screening), evaluate optional measurements against EWGSOP2 cutoffs (grip <27 kg men / <16 kg women; gait <0.8 m/s; calf <34 cm men / <33 cm women), compute BMI and a personalised protein target, and assign an overall risk level with exercise, nutrition, and testing guidance.

Question 11

When should I see a doctor about sarcopenia risk?

Accepted Answer

See your doctor if: SARC-F score ≥4, unintentional weight loss >5% in 6 months, frequent falls (≥2 in a year), sudden difficulty with stairs or rising from chairs, grip strength noticeably declining, or multiple risk factors on this calculator. Also seek care if you have diabetes, heart failure, or kidney disease with declining mobility. Early intervention prevents falls, fractures, and loss of independence.

Question 12

Is this calculator a diagnosis of sarcopenia?

Accepted Answer

No. This is an educational screening tool based on the validated SARC-F questionnaire and known risk factors—it is not a substitute for medical evaluation. Sarcopenia diagnosis requires clinical measurement of grip strength, gait speed, and body composition by a qualified healthcare provider. Do not start or stop medications or exercise programmes based solely on calculator results. If you have sudden weakness, falls with injury, or unexplained weight loss, seek medical care promptly.
