Possible causes
- 01
Hyperthyroidism
commonAn overactive thyroid gland accelerates the body's metabolic rate, leading to increased heat production, sweating, weight loss, and anxiety.
Evidence
- NICE CKS: Hyperthyroidism (2021)
- 02
Perimenopause or Menopause
commonFluctuating estrogen levels disrupt the brain's thermoregulatory center, causing sudden hot flushes and night sweats.
Evidence
- NICE: Menopause: diagnosis and management (NG23)
- 03
Primary or Secondary Hyperhidrosis
possibleAn overactivity of the sweat glands, which can be localized (primary) or generalized due to medications, infections, or underlying conditions (secondary).
Evidence
- NHS: Excessive sweating (hyperhidrosis) guidelines
Recommended tests
Thyroid function panel
→TSH, Free T3, Free T4 — first-line test for fatigue, weight change, hair loss, mood.
Why: To measure TSH, Free T3, and Free T4 to rule out hyperthyroidism as a primary metabolic cause.
Guideline
- NICE CKS: Thyroid function tests (2023)
Female hormone panel
→Oestradiol, progesterone, FSH, LH, prolactin, testosterone — cycle, PCOS, perimenopause.
Why: To evaluate FSH, LH, and oestradiol levels if perimenopause or ovarian insufficiency is suspected.
Guideline
- NICE: Menopause Guideline NG23
GP consultation
→30–60 minute consultation with a British-trained GP — clinic, home or video.
Why: For a comprehensive physical exam, medication review, and tailored diagnostic planning.
Guideline
- RCGP: Primary Care Consultation Standards
When to worry
- Unexplained weight loss despite an increased appetite
- Rapid, irregular, or pounding heartbeat (palpitations)
- New or worsening tremors, severe anxiety, or muscle weakness
