Hormone replacement therapy (or HRT) (also known as menopausal hormone therapy; MHT) is the replacement of female sex hormones oestrogen and progesterone in women to control symptoms of the menopause.
Ghrelin is termed the ‘hunger hormone’ and tells our brain that we’re hungry. It is produced by the stomach where it promotes appetite, how food is turned into energy and storage of fat.
Leptin is produced by fat cells when we eat and signals to the brain that we’re full.
Endocrinology is the study of hormones.
