Sleep

Conditions

• Acid reflux and GERD Reflux is a mechanical story — a one-way valve losing its seal — with fixes that are mostly mechanical too, a drug class that works best used precisely, and a short alarm list that separates nuisance from endoscopy.
• Insomnia Chronic insomnia is a learned disorder — a bed that has become a cue for wakefulness — which is exactly why the treatment that unlearns it beats every pill in trials, and why nobody profitable tells you so.
• Memory loss and aging Slower word-finding at 60 is aging. Forgetting the conversation happened is not. The line between the two is clearer than most people fear — and a surprising share of what crosses it is reversible.
• Menopause and perimenopause Menopause is a decade-long neurological and hormonal transition, not a single event — and its treatment story is one of medicine's great pendulum swings, now settling somewhere far more useful than either extreme.
• Obesity and overweight Obesity is a chronic, relapsing, biologically defended condition — not a character audit. Treating it like the first and not the second is what modern care gets right.
• Sleep apnea Obstructive sleep apnea is this site's most-referenced diagnosis for a reason — it hides inside fatigue, fog, hypertension and low hormones, half its sufferers don't know they have it, and treating it is one of medicine's fastest turnarounds.
• Tinnitus Tinnitus is not a sound in the ear but a signal in the brain — the auditory system turning up its own volume when input fades. That reframe explains both why no pill silences it and why real help exists anyway.

Symptoms

• Brain fog Brain fog is not a diagnosis; it is a description — and in most people it points away from the brain, toward sleep, mood, hormones, medications or inflammation. That is good news, because those are fixable.
• Chronic cough A cough past eight weeks stops being a cold's tail and becomes a puzzle with surprisingly few pieces — three common causes, one famous medication, and a short red-flag list that decides who needs a chest X-ray this week.
• Fatigue Fatigue is medicine's most common complaint and least specific — but it sorts fast under three questions: sleepy or weary, rested by sleep or not, and what does it keep company with. The answers route almost everyone somewhere useful.
• Frequent urination at night (nocturia) Getting up once a night is common and usually harmless. Twice or more is worth investigating, because the cause is as often in the kidneys, heart or sleep as in the bladder.
• Heart palpitations Most palpitations are the heart's normal glitches felt by an attentive brain — and a specific minority are a rhythm worth catching for its stroke stakes. Pattern, company and a well-timed recording sort one from the other.
• Signs of low testosterone Every tired man has seen the checklist that ends in a supplement. Here is the honest version — which signs actually track with testosterone, and which are usually sleep, stress, weight or mood wearing a hormonal costume.
• Muscle cramps The classic cramp story — "you're low on something" — is mostly wrong: cramps are nerves misfiring, not tanks running empty, which is why stretching outperforms most supplements and why the magnesium verdict disappoints.

Ingredients

What the evidence says about ingredients commonly used in this area.

• Ashwagandha Ashwagandha is the rare supplement whose flagship claim — lower perceived stress — has repeated placebo-controlled support. Its other claims ride further from the evidence, and its safety story has acquired a footnote.
• Magnesium Magnesium is involved in hundreds of enzyme reactions, and low levels are common in people with type 2 diabetes. That is why it helps some people and not others — the benefit depends on where you start.
• Melatonin Melatonin is the most misunderstood molecule in the sleep aisle — a darkness signal that tells the clock when night is, taken by millions as a knockout drop it never was, in doses the research never used.

Questions people ask

• Can stress raise blood sugar? Yes — and the mechanism is the same one that lets you run from a threat. The problem is that modern stress rarely involves running.
• Do sleep supplements work? The sleep aisle sells sedation; the trials mostly show nudges — a clock signal, a few relaxants with small files, and blends built for the checkout. Meanwhile the treatment that actually beats pills isn't on any shelf.
