Hormones

What are hormones?

DotS the definition of hormones may vary. The (United States) Endocrine Society’s definition is:

“Hormones–Made by endocrine glands, hormones are chemical messengers that travel in the bloodstream to tissues or organs. They affect many processes, including growth, metabolism, sexual function, reproduction, and mood”.2

The (Australian) Jean Hailes for Women’s Health’s (JH) definition is:

“Hormones are chemicals made in your body that relay messages through your bloodstream. For example, your hormones tell your body to eat and sleep”.3

Menopause

What causes menopause?

In What Is Perimenopause and Menopause? What Causes Menopause? the JH explain:

“Menopause is caused by a drop in certain hormones such as oestrogen. From about 35 to 40 years of age, you have fewer eggs left in your ovaries and don’t ovulate (release an egg from your ovary) as often. Menopause means your ovulation and periods stop.

The main hormones that change as you approach menopause are oestrogen and progesterone”.4

Oestrogen

What does oestrogen do?

The JH note:

“Oestrogen is produced from the cells around the eggs in your ovaries. It is one of the main female sex hormones. Oestrogen plays an important role in the female body. For example, it’s needed for the menstrual cycle, fertility, pregnancy and bone strength. It also helps with brain function and bladder control and protects you from heart disease.

Your oestrogen production changes in the lead-up to menopause. As you approach your final period, your number of eggs decreases, and oestrogen levels drop by up to 90%”.5

Progesterone

What does progesterone do?

The JH explain:

“Progesterone is responsible for things like mucus levels in your cervix, acidity levels in your vagina and milk cells in your breasts. It can also impact your mood.

Progesterone is produced when an egg is released. It prepares your uterus for a fertilised egg and pregnancy. As you approach your final period, your progesterone levels decrease”.6

Health Care Provider

What if I need help with my hormones?

If you need help with your hormones, it may be in your best interest to choose to talk to your health care provider about this. Together you can clarify your signs and symptoms, discuss your options and if required, agree on who may be the most appropriate health care provider to help you.
