Can Hormones in the Kidneys Affect Menopause?
Estrogen, also known as the “female sex hormone,” plays a significant role in keeping the body functioning well. You need estrogen for immune system management, menstrual cycle regulation, and cardiovascular health, to name a few.
Hormonal imbalances are a normal part of how your body operates and are a normal part of your body regulating your system throughout life. Hormonal imbalances don’t always cause symptoms, but when they do, it can be a sign of an underlying health condition. In the kidneys, hormones like estrogen assist in blood pressure management and ensuring your kidneys work efficiently.
Women with very low estrogen levels may see changes in their health as their hormones fluctuate. Some women may experience hormonal imbalances and kidney complications when approaching menopause. While menopause does not always directly affect hormones in the kidneys, women with preexisting kidney disease may have more difficulties managing menopausal symptoms.
What Hormones are Produced in the Kidneys?
The kidneys produce three main hormones: renin, erythropoietin (EPO), and vitamin D3 (calcitriol). The kidneys also produce the following hormone-like substances:
Natriuretic peptides
Prostaglandins
Endothelins
Adrenomedullin
Renin
Several different groups of cells are involved in the release of renin. Cyclic GMP, calcium ions, and cyclic AMP (cGMP) all play a role in releasing renin. Cyclic AMP serves as a messenger between cells to activate proteins, while cGMP and calcium ions stimulate the release of renin in the kidneys.
Erythropoietin (EPO)
Pericytes (multifunctional cells in the body) create erythropoietin in the process of helping to transport oxygen to the kidneys.
1,25-dihydroxyvitamin D3 (calcitriol)
The process of producing calcitriol occurs in the skin, liver, and kidneys. Calcitriol is created when the skin is exposed to sunlight and other sources of vitamin D. From there, vitamin D3 is absorbed into the bloodstream and activated in the liver and kidneys.
RAAS (renin-angiotensin-aldosterone system)
Estradiol (a form of estrogen) helps to form RAAS. The hormone-like substance RAAS (renin-angiotensin-aldosterone system) is a system produced in the kidneys.
What is the Purpose of Hormones Produced in the Kidneys?
Hormones help the kidneys carry out essential functions that take place outside of the kidneys as well. The kidneys are responsible for filtering out blood, regulating blood pressure, and preventing a build-up of waste.
Renin function
Renin helps to control blood pressure and balance fluid in the kidneys.
Erythropoietin (EPO) function
In the kidneys, the hormone erythropoietin stimulates the production of red blood cells. Those with anemia, chronic kidney disease, or who have had surgery recently may see a decline in red blood cells.
Healthcare providers may prescribe man-made EPO to patients with low hemoglobin. Premenopausal women with certain health conditions may experience more fatigue without enough erythropoietin.
1,25-dihydroxyvitamin D3 (calcitriol) function
Calcitriol helps to produce calcium in the blood. Menopausal women may also experience lower vitamin D from a lack of calcitriol in the kidneys. In severe cases, vitamin D deficiency may result in weaker bones.
A healthcare professional may prescribe calcitriol to treat low levels of calcium in those with bone disease, kidney disease, and other calcium complications.
RAAS (renin-angiotensin-aldosterone system) function
The main function of RAAS is to regulate blood pressure, balance electrolytes, and manage fluid in the kidneys.
Estrogen influences RAAS and plays a key role in regulating bodily processes managed by the kidneys. When estrogen levels are low during menopause, it can be more difficult for the RAAS to function properly. That’s why women with low estrogen levels may have an increased risk of developing hypertension and other cardiovascular complications.
What Happens When You Have Kidney Complications
When the kidneys are having difficulty functioning efficiently, their hormone production can be affected. In the late stages of chronic kidney disease, when the kidneys can no longer function well on their own without medical treatment, the hormonal changes often become more pronounced.
Menopause does not always affect the kidneys, but the following kidney complications may affect the severity of menopausal symptoms and hormonal health in women:
Chronic kidney disease (CKD): The kidneys are damaged for at least three months before it's considered chronic kidney disease. Chronic kidney disease occurs in five stages. Those with chronic kidney disease may not experience symptoms until they enter the later stages of it.
Kidney failure: The kidneys can no longer function efficiently on their own. Those with kidney failure require a kidney transplant or dialysis.
Kidney complications can lead to imbalances with insulin, sex, and thyroid hormones. Chronic kidney disease can negatively affect bone health in postmenopausal women and may increase the risk of a woman going through menopause before the age of 45.
Some women may experience more menopausal symptoms from changes in kidney function. Because of the risk of severe hormonal imbalance with CKD, a healthcare provider may more closely monitor postmenopausal women with chronic kidney disease as they approach menopause. Health experts are conducting more research to confirm whether there is a connection between CKD and early menopause.
Is Hormone Replacement Therapy Used for the Kidneys?
Hormone replacement therapy (specifically menopausal hormone therapy) is not a treatment for kidney complications. However, researchers have looked into how estrogen replacement therapy may help postmenopausal women with kidney disease better manage their menopausal symptoms.
HRT for menopause is available in tablet, patch, spray, gel, and injection form. While HRT may be beneficial for postmenopausal women with kidney disease, health experts are conducting more research to assess the cardiovascular risk. Be sure to check with a licensed healthcare provider before starting HRT if you have a history of kidney complications.
Quick Tips for Managing Hormonal Imbalances
It’s normal for your hormones to fluctuate from time to time. Most hormonal imbalances don’t cause symptoms. But health conditions like kidney disease, thyroid complications, and more can cause symptoms to develop in postmenopausal women.
The following healthy habits may help you keep your hormones balanced and reduce the severity of menopausal symptoms:
Eat a well-balanced, low-sodium diet
Stay hydrated
Prioritize more vitamin C and D
Engage in physical activity daily
Avoid drinking alcohol excessively
