GLP-1 receptor agonists have been in clinical use since 2005. This evidence-based review covers the full safety record, major trials, FDA warnings, and what patients starting these medications should know.
Mounjaro (tirzepatide) is not approved for general weight loss in all adults. Learn who qualifies, who should avoid it, what the clinical data show, and how to find out if you are a candidate.
Learn which blood tests, symptoms, and clinical criteria doctors use to diagnose perimenopause, what FSH, estradiol, and AMH levels mean, and when hormone testing actually helps.
GLP-1 receptor agonists slow gastric emptying, which can reduce or delay the absorption of oral medications taken at the same time. Learn which drugs are most affected, what the clinical data show, and how to time your medications safely.
Levothyroxine restores thyroid hormone levels in hypothyroidism, which can reverse the weight gain caused by a slow metabolism. But for people with normal thyroid function, it does not produce meaningful fat loss and carries real risks. Read the full clinical picture.
Yes, menopause can cause hair loss. Falling estrogen and progesterone levels shift hair follicles into a resting phase while rising androgen activity shrinks them. Learn the mechanisms, treatment options, and what the evidence actually shows.
Yes, menopause causes fatigue through falling estrogen, disrupted sleep, and thyroid overlap. This evidence-based guide covers why it happens, how to confirm the cause, and what actually works to restore energy.
Diagnosis requires a TSH blood test plus TPO antibody testing, positive in about 95% of cases. Ultrasound confirms borderline results per ATA guidelines.
Learn the clinical signs, lab markers, and evidence-based strategies to identify a slowing metabolism, including thyroid function, hormonal changes, and actionable next steps.
Body-type dieting lacks clinical evidence. Learn what actually predicts dietary success, including thyroid function, insulin sensitivity, and metabolic markers, plus how to match your eating pattern to your biology.
After 40, hormonal shifts, muscle loss, and metabolic slowdown make standard calorie-cutting ineffective. Learn what the clinical evidence actually supports for sustainable fat loss at this life stage.
Learn how to interpret TSH, free T4, free T3, testosterone, estradiol, and other hormone lab values. Understand reference ranges, optimal zones, and when results signal a need for treatment.
