Men's health
Heart, sleep, liver, kidneys, hormones, sex and habits, explained with sources for men taking a GLP-1 medicine.
Heart and metabolism
Blood pressure on these medicines
Why some men feel dizzy, what the labels say about low blood pressure, and why blood pressure and erection medicines deserve a conversation.
Blood sugar and diabetes
For men with type 2 diabetes: low blood sugar with insulin or sulfonylureas, eye follow-up, and why the weight change tends to be smaller.
Heart failure: what the studies showed
SUMMIT, a trial of tirzepatide in heart failure with preserved ejection fraction and obesity: the numbers, the limits, and what to ask.
Heart: what the studies showed
SELECT, a heart trial where 72% were men, in absolute numbers: who took part, what happened, who it applies to and whether it's on the label.
Sleep
Sleep apnea: what the studies showed
The SURMOUNT-OSA trials in plain numbers, who they apply to, and where sleep apnea is an approved use.
Liver and kidneys
Kidneys: what the studies showed
FLOW, a trial in people with type 2 diabetes and kidney disease, plus what matters for kidneys day to day: fluids and protein.
Liver: what the studies showed
ESSENCE, a biopsy trial of semaglutide in fatty liver disease with scarring: the numbers, who took part, what's still unknown and where it's on the label.
Hormones and sex
Desire: what's known and what isn't
What the small studies and drug safety reports show about desire on these medicines, and how to track it privately.
Erections: what's known and what isn't
Studies point both ways and none proves cause. What the labels say, how erection medicines fit in, and when a change is worth a visit.
Fertility and trying for a baby
None of the US or European labels tells men to stop before trying for a baby. What the labels and the few human studies say, and where testosterone therapy changes things.
Testosterone and GLP-1
What happens to testosterone as weight comes off, what the studies can and can't say, and how testosterone therapy fits in.
Habits
Alcohol and GLP-1: the evidence
What alcohol does on these medicines, what the drinking trials found in numbers, and why it isn't an approved use.
Smoking and GLP-1
There's no proof these medicines help people quit smoking. What two 2026 studies found, and the one effect that may matter if you quit.
The gym and supplements
Training on GLP-1 medicines, protein without the arms race, and what the evidence says about creatine, protein shakes and 'peptides'.
Body
Hair, face and skin
Hair loss is rare in men on these medicines. What the labels show, what's known about the face and skin, and when to see someone.
Muscle image and compulsive exercise
When training and the mirror start running your days. The signs worth noticing in men, and why short questionnaires may miss them.
Prostate and urinary health: what we know
The GLP-1 labels reviewed don't mention the prostate. Here's what the data do show, including kidney stones, and where testosterone therapy comes in.
Medicines
Other medicines alongside
Blood pressure pills, insulin, warfarin, thyroid tablets, testosterone and erection medicines: what the labels say about taking them together.
Unregistered products
Compounded, online, imported or 'research' products: what tests and regulators found, the signs worth knowing, and how to tell your doctor.
