GLP-1s and Type 1 Diabetes

Comorbidities

GLP-1s and Type 1 Diabetes

This is the off-label corner of the field. The rationale is real, the trials were mixed, and the risk that matters is one you can walk into by eating less: ketoacidosis with a glucose that looks fine.

GLP-1s and Skin Conditions

Comorbidities

GLP-1s and Skin Conditions

Hidradenitis suppurativa and psoriasis both track weight in ways most patients are never told about. If you have either, this is one of the more concrete reasons to be on this medication.

Thyroid Disease on a GLP-1

Comorbidities

Thyroid Disease on a GLP-1

Levothyroxine is dosed by body weight, which means your dose was calculated for a body you no longer have. Almost nobody rechecks, and the symptoms of getting it wrong look exactly like the drug working.

GLP-1s and Gout

Comorbidities

GLP-1s and Gout

Long-term weight loss lowers uric acid and reduces gout attacks. Getting there can provoke one, which is a genuinely unfair sequence and an entirely predictable one.

GLP-1s and Bariatric Surgery

Comorbidities

GLP-1s and Psychiatric Medications

Some of the most effective drugs in psychiatry cause substantial weight gain, and the people taking them are routinely told to eat less by clinicians who know perfectly well that is not what is happening.

GLP-1s and Knee Osteoarthritis

Comorbidities

GLP-1s and Knee Osteoarthritis

Every extra kilogram lands on the knee several times over with each step, which is why the joint that hurts is usually the one carrying the most. There is now a randomised trial for this, and the result is better than most people expect.

GLP-1s and Fatty Liver Disease

Comorbidities

GLP-1s and Fatty Liver Disease

The commonest liver disease in the world has no approved drug for most of the people who have it, and a large share of them are sitting in front of a prescription that treats the thing causing it.

GLP-1s and Sleep Apnea

Comorbidities

GLP-1s and Sleep Apnea

Tirzepatide now carries an approved indication for obstructive sleep apnea, on the strength of a trial that cut the severity measure by about half. The practical consequence catches people out: your CPAP pressure is now wrong.
