Like estrogen, progesterone interacts with the chemicals in your brain to control your mood and your general sense of well being. A way that progesterone does this is via its metabolite, a compound known as allopregnanolone. Allopregnanolone works on a particular receptor in your brain called the GABA receptor. Typically it has anxiety busting action and a calming quality similar to the actions of alcohol and other sedative drugs like the benzodiazepines. This is why you may feel sleepy or a little low energy right before your period or during the early part of pregnancy.
Many hormones and their structural and functional analogs are used as medication . The most commonly prescribed hormones are estrogens and progestogens (as methods of hormonal contraception and as HRT ),  thyroxine (as levothyroxine , for hypothyroidism ) and steroids (for autoimmune diseases and several respiratory disorders ). Insulin is used by many diabetics . Local preparations for use in otolaryngology often contain pharmacologic equivalents of adrenaline , while steroid and vitamin D creams are used extensively in dermatological practice.
Imbalances in your hormones are triggered by bad food. If you eat sugar, you’ll produce more insulin, more estrogen, and more testosterone. Any type of flour and sugar can lead to these imbalances. Dairy and gluten are often triggers for inflammation and hormonal imbalances. Xenobiotics or environmental chemicals like pesticides in our food can act like powerful hormone disruptors and trigger our own hormones to go out of balance.
