Understanding your health, one topic at a time
Guides on symptoms and the tests that explain them, how to read your results, what your watch and home measurements say, longevity and cycle. With sources, without medical promises and without selling miracles.
High cholesterol: what it means, when to worry and what to ask for
You searched for high cholesterol symptoms and there are none. What LDL, HDL and non-HDL mean, which thresholds guidelines use and what to bring to your doctor.
High triglycerides: what the number means and what to check before repeating the test
High triglycerides in your results: what each band means, why they change with dinner and alcohol, and what to check before repeating the test.
High creatinine: what it means, what raises it without the kidney, and what to ask for
Your creatinine came out high on a blood test. What raises it without the kidney being involved, what eGFR is, why it is repeated in three months and what to ask for.
Brain fog: what it is, which causes can be measured and which tests to ask for
You think slowly, words slip away, you cannot focus. Which part of brain fog is measured at home, which blood test makes sense to ask for and when not to wait.
Tingling in hands and feet: causes, which tests to ask for and when not to wait
Tingling in hands and feet: why the pattern (where, when, with what) says more than a random blood test, which tests are considered and when not to wait.
Sleepy after meals and craving sugar: glucose, insulin and the pattern almost nobody measures
Sleepiness after meals, sugar cravings and the afternoon crash: what is normal, what points to glucose and insulin, which tests measure it and how to log it at home.
Fatigue: causes and which tests to ask for
You have been tired for months and the blood tests you had came back normal. Which tests are usually checked first, what they tend to show and how to log your fatigue so the appointment is useful.
Frequent headaches: causes, what to measure at home and when to worry
Your head hurts several times a month and the blood test came back normal. Why it almost never shows in the blood, what you can measure at home (days with pain, blood pressure, sleep, caffeine, cycle) and which signs cannot wait.
Hair loss: causes and which tests to ask for
You are losing more hair than usual and do not know whether to ask for a blood test, see a dermatologist or wait. The three tests usually checked (ferritin, TSH, blood count), the timeline that explains most cases and how to log it.
Why the laboratory reference range is not your personal norm
The lab range describes a population, not you. What those numbers in brackets actually mean and how to read them alongside your own history.
What biological age is and how it is calculated
Biological age estimates how your body is working, not how long you have left. What PhenoAge measures, which nine blood markers it uses, and how to read the result without over-reading it.
How to read your lab results without panicking
A flagged value is not a diagnosis. What moves your results when nothing is wrong, why something almost always comes back out of range, and how to read your report in five steps.
