How Hormones Affect the Body Imbalance Symptoms, Causes, Diagnosis,

What are hormones?

Hormones are chemicals that coordinate different functions in the body carrying messages through your blood to your organs, skin, muscles and other tissues. These signals tell your body what to do and when to do it. Hormones are essential for life and your health.

Scientists have identified over 50 hormones in the human body so far.

Hormones and most of the tissues (mainly glands) that create and release them make up your endocrine system. Hormones control many different bodily processes, including:

Metabolism.
Homeostasis (constant internal balance).
Growth and development.
Sexual function.
Reproduction.
Sleep-wake cycle.
Mood.

What is a hormonal imbalance?

A hormonal imbalance happens when you have too much or too little of one or more hormones. It’s a broad term that can represent many different hormone-related conditions.

Hormones are powerful signals. For many hormones, having even slightly too much or too little of them can cause major changes to your body and lead to certain conditions that require treatment.

Some hormonal imbalances can be temporary while others are chronic (long-term). In addition, some hormonal imbalances require treatment so you can stay physically healthy, while others may not impact your health but can negatively affect your quality of life.

Symptoms and Causes

Because your body makes over 50 different hormones — all of which contribute to important bodily functions — you could experience several different symptoms depending on which hormonal imbalance you have.

It’s important to know that many of the following symptoms could be caused by other conditions, not just from a hormonal imbalance. If you ever notice a change in your day-to-day health and are experiencing new, persistent symptoms, it’s important to talk to your healthcare provider — no matter what you think the cause might be.

Hormone imbalance symptoms that affect your metabolism

Common hormonal imbalances include those that affect your metabolism. Your metabolism consists of the chemical reactions in your body's cells that change the food you eat into energy. Many different hormones and processes are involved in metabolism.

Symptoms of hormonal imbalances that affect your metabolism include:

Slow heartbeat or rapid heartbeat (tachycardia).
Unexplained weight gain or weight loss.
Fatigue.
Constipation.
Diarrhea or more frequent bowel movements.
Numbness and tingling in your hands.
Higher-than-normal blood cholesterol levels.
Depression or anxiety.
Being unable to tolerate cold temperatures or warm temperatures.
Dry, coarse skin and hair.
Thin, warm and moist skin.
Irregular body fat distribution.
Darkened skin in your armpit or the back and sides of your neck (acanthosis nigricans).
Skin tags (small skin growths).
Extreme thirst and frequent urination.

Sex hormone imbalance symptoms for people assigned female at birth

People assigned female at birth (AFAB) can have imbalances of the sex hormones estrogen and progesterone, which the ovaries produce. They can also have excess testosterone and androgens. An imbalance in sex hormones can cause the following symptoms in people AFAB:

Acne on your face, chest and/or upper back.
Hair loss.
Heavy periods.
Hirsutism (excess body hair).
Hot flashes.
Infertility.
Irregular periods.
Loss of interest in sex.
Vaginal atrophy.
Vaginal dryness.

Sex hormone imbalance symptoms for people assigned male at birth

People assigned male at birth (AMAB) can have an imbalance of testosterone, which the testes produce, and other sex hormones, which can cause the following symptoms:

Decrease or loss of body hair.
Erectile dysfunction (ED).
Gynecomastia (enlarged breast tissue).
Infertility.
Loss of interest in sex.
Loss of muscle mass.

Can hormone imbalance cause weight gain?

Yes, certain hormone imbalances can cause weight gain, including:

Hypothyroidism: This condition happens when you have low levels of thyroid hormone, which causes your metabolism to slow down. This can cause weight gain.
Cushing’s syndrome: This is a rare condition that happens when your body has too much of a hormone called cortisol. It results in rapid weight gain in your face (sometimes called “moon face”), belly, back of your neck (sometimes called “buffalo hump”) and chest.
Menopause: During menopause, many people assigned female at birth gain weight due to hormonal changes that cause their metabolism to slow down. It’s important to remember that this type of “hormonal imbalance” is natural and an expected part of life.

Several other factors contribute to weight gain. If you’re experiencing unexpected weight gain or are concerned about your weight, talk to your healthcare provider.

Can hormone imbalance cause anxiety?

Yes, certain hormonal imbalances can cause anxiety, including:

Hyperthyroidism: If you have hyperthyroidism, it means your body has too much thyroid hormone. Excess thyroid hormone speeds up your metabolism. This can cause anxiety, in addition to unusual nervousness, restlessness and irritability.
Cushing’s syndrome: While it’s not as common of a symptom, Cushing’s syndrome (excess cortisol) can cause anxiety, as well as depression and irritability.
Adult-onset growth hormone deficiency: Adults with growth hormone deficiency often report having anxiety and/or depression.

Several other conditions and factors can cause anxiety. It’s important to talk to your healthcare provider if you’re experiencing anxiety.
