Body composition · Northern Ireland & Donegal
A Tanita body composition scan estimates body fat, muscle, visceral fat, body water and metabolism, with a detailed report you can keep. Available at our Greysteel and Letterkenny clinics.
Not suitable if you have a pacemaker or other implanted electronic device. Tell us if you are or may be pregnant.
What the monitor estimates
Estimate how much of your overall weight is body fat, shown as both a percentage and a mass.
Review an estimate of deeper abdominal fat around the organs, which weight and appearance cannot show.
Understand estimated muscle mass rather than assuming every change on the scale is fat gain or loss.
Compare estimated muscle and fat distribution across the arms, legs and trunk where supported by the monitor.
See an estimate of the proportion of your body made up of water and recognise why hydration affects the result.
Review calculated basal metabolic rate, metabolic age and estimated bone mass alongside the wider report.
What BIA adds
Losing fat and gaining muscle may barely move an ordinary scale. Body composition analysis separates those estimates, giving a more useful baseline for health, training or weight management.
It is an estimate, not a diagnosis. It is most useful for consistent monitoring over time.
| Measure | What it shows | What it can’t show |
|---|---|---|
| Body weight | Your total mass | Fat, muscle and water distribution |
| BMI | Weight relative to height | Individual body composition |
| Tanita BIA | Estimated fat, muscle and water | A diagnosis or medical imaging |
Important: estimated bone mass is not a bone density test, and the visceral fat rating is not an abdominal scan.
Your appointment
The measurement itself is brief. Good preparation and consistent conditions make the results more useful.
Follow the instructions provided before your appointment so food, exercise and hydration have less effect on the reading.
Remove shoes and socks, enter the required details and stand still while the Tanita monitor takes the measurement.
Your results are organised into a detailed report explaining the measurements that are relevant to your scan.
Repeat under similar conditions when appropriate so the comparison is more meaningful than a single reading.
Preparing for your scan
Hydration and recent activity can shift BIA estimates. Follow the instructions we send with your booking.
Do not have a BIA scan with a pacemaker or implanted electronic medical device. Contact us before booking if you are pregnant or unsure whether the assessment is suitable.
Avoid arriving severely dehydrated or straight after drinking a large volume.
Allow your body to recover before the measurement.
Follow the timing advice supplied with your appointment.
Shoes and socks are removed for electrode contact.
Who it can help
The assessment can stand alone or add a baseline to a wider health, fitness or weight-management plan.
See whether progress is more consistent with changes in estimated fat, muscle or body water—not simply total weight.
Monitor muscle distribution and body-composition trends alongside a training or nutrition programme.
Build a broader snapshot of your current composition before making planned lifestyle changes.
Keep muscle mass and fat distribution visible as strength, mobility and long-term health become priorities.
Following a weight management programme? Body composition trends can add context by separating estimated fat, muscle and water changes. Medical weight loss
