Nine Medichecks blood panels (2018-2026) and a June 2026 clinical assessment, read against weight, training, steps and sleep (2021-2026)
Most markers have been steady and healthy across nine tests since 2018. The signal is in a few moving parts: weight, lipids, a clear deconditioning dip in 2024 you have since reversed, two transient inflammation spikes, and a borderline ECG finding from 2025.
HbA1c has stayed non-diabetic at every test (24-35 mmol/mol). Jun 2025 (35) was the highest, at peak weight; the latest (Jun 2026, 24) is the lowest on record, in step with the recent weight loss. Thyroid broadly normal and vitamin D consistently good at 86-127, so supplementation is working.
Total cholesterol and LDL sit around their thresholds and move with lifestyle. Worst was Jun 2021 (total 5.4, LDL 3.5, both flagged); best total was Jun 2025 (4.19). LDL mostly held at 2.5-2.6 but crept to 2.99 in Jun 2026, just under the limit. HDL stays protective (1.1-1.5). A repeat once weight settles will show where they land.
Logged training collapsed to 78 hours (vs 300-580 in other years) and steps fell to ~4,460/day, the lowest on record. Weight drifted from ~92kg to ~98kg across 2024 into early 2025. You have since rebuilt volume hard through 2025-2026.
It climbed from 14.6 nmol/L (2019) to a peak of 18.5 (2024), then settled to 15.8 (2025) and 15.6 (2026) as weight rose, all firmly mid-range and healthy. Kidney function improved markedly too: early high creatinine and low eGFR settled into a healthy range from 2022.
Bilirubin has been mildly raised at every single test (24-44), the classic Gilbert's syndrome picture noted by several reviewing doctors. Haematocrit and total protein/albumin run high-normal, consistent with a well-trained endurance athlete sometimes dehydrated at the draw.
The Jun 2026 assessment found borderline first-degree heart block and right bundle branch block, otherwise normal sinus rhythm. The 2025 assessment noted the same, with no significant change since 2023-2024, so it appears longstanding and stable. Usually harmless and symptomless; the clinic advised monitoring and review if dizziness, fainting, chest pain or breathlessness appear.
Monthly average from LoseIt. Broadly stable in the low 90s through 2021-2023, a rise through the low-activity stretch of 2024 into 2025, and a sharp fall in the last few weeks since starting Mounjaro on 29 May 2026.
From your Withings Body Comp scale: monthly averages of ~850 readings. Body fat has held in a tight, athletic 17-23% band for seven years, latest 21.2% (25 Jun 2026), nowhere near the clinic's 28.2% bioimpedance figure, which now clearly looks like a measurement error. Muscle mass has stayed around 70-72kg and visceral fat low throughout, including through the current weight loss, which is exactly the lean-mass preservation you want on a GLP-1.
Pick any marker to see its 2018-2026 trajectory against its reference band (green). Red points are values flagged outside the lab range that year.
The four lipids that matter together. The goal pattern is total and LDL trending down, HDL holding up, and the total:HDL ratio low. 2024-2025 gave the cleanest profiles; LDL nudged up again to 2.99 in Jun 2026.
Your most recent in-person assessment (4 Jun 2026, about a week into Mounjaro) at 97.5kg, graded on a green / amber / action-required flag system. The same MOT a year earlier (5 Jun 2025) gave consistent findings. The clinic flagged body composition and ECG amber; the body-fat reading looks erroneous (see below), so on a corrected basis the ECG is the only amber item.
97.5kg, BMI 26.9, muscle mass 66.5kg (healthy >49kg). The clinic flagged body fat at 28.2% (amber), but that was taken on basic bioimpedance scales which tend to overread. Your Withings scale has logged body fat in a 17-23% band for seven years (21.2% on 25 Jun 2026), far more consistent with your training and muscle mass. See the body-composition section above for the full trend. BMI stays a little high mainly because heavy muscle inflates it. Advice: maintain the regime, with adequate protein and carbohydrate for recovery.
129/86 mmHg and SpO₂ 99%. BP fell with each of three successive readings, settling in the normal range. Oxygen delivery healthy. Suggestion: pick up an inexpensive home BP monitor and check every few months to catch any trend early.
FVC 5.64 L (healthy >2.85) and FEV1 4.61 L (healthy >2.4), both well above range. No obstruction or restriction; lungs are not a limiting factor for exercise.
Borderline first-degree heart block and right bundle branch block, otherwise normal sinus rhythm and no change since 2023-2024. Both are commonly harmless. Monitor for now; seek review if dizziness, fainting, a missed-beat sensation, chest pain or breathlessness occur.
Past surgery, a sport-limiting musculoskeletal injury and an eye injury noted; no cardiac symptoms or family cardiac history. Judo twice weekly plus cycling one to three times meets NHS activity guidelines. Stated goal: keep some cardiovascular work going each week given the desk-based job.
The behaviours behind the numbers. 2024 stands out across the board: least training, fewest steps. Logged training hours depend on what was recorded, so treat them as a floor not a ceiling.

Your lipid profile swings with training and body composition. With a fast Mounjaro-driven drop underway, a repeat in a few months will show where total cholesterol and LDL settle and whether the borderline readings resolve.
Losing ~1kg/week on a GLP-1 risks shedding muscle alongside fat, and you started at 66.5kg muscle. Kettlebells and judo are the defence. The LoseIt protein log is incomplete, so intake is unverifiable; logging it deliberately for a fortnight would make adequacy visible. Confirm targets with the prescriber.
Free thyroxine was just over range in Jun 2026 (22.2, limit 22) with normal TSH and T3. The reviewing doctor suggested repeating thyroid function in three months, especially if any symptoms (palpitations, heat intolerance, unexplained loss) appear.
Two threads from 2025 to close: the borderline ECG (first-degree block plus RBBB) flagged for monitoring, and the raised CRP (9.52, attributed to a knee) the lab wanted rechecked in 6-8 weeks. The latest CRP (1.2) is normal, so worth confirming the repeat was done and the ECG plan with your GP.
Nine years of mildly raised bilirubin with otherwise normal liver markers is the textbook Gilbert's pattern. Worth a one-line confirmation with your GP if never formally discussed, but not a concern.
