What Are the Symptoms of Low Testosterone? Signs to Watch For

Testosterone is often referred to as the "male hormone," but its role in the body goes far beyond gender. It is a crucial hormone for both men and women, influencing physical health, emotional balance, and mental clarity. For men, testosterone production typically peaks in early adulthood and gradually decreases with age. While some decline is natural, excessively low levels—known as low testosterone or low T—can lead to significant health issues.

In this blog, we’ll explore what testosterone does, the key symptoms of low testosterone, its potential causes, and how it can be treated. By understanding these signs and symptoms, you can take steps to address any concerns and improve your overall well-being.

The Role of Testosterone in the Body

Testosterone is produced primarily in the testes for men and in smaller amounts in the ovaries and adrenal glands for women. It plays a vital role in many bodily functions. For men, testosterone is most closely associated with traits like muscle growth, a deep voice, and facial hair. However, it does much more than this.

Testosterone supports muscle maintenance, bone strength, and the production of red blood cells. It also plays a critical role in energy levels, mental focus, and emotional stability. In addition, testosterone is essential for sexual health, including libido and reproductive function.

For women, although testosterone is present in lower levels, it is equally important. It helps maintain bone density, supports sexual health, and contributes to overall energy and mood.

When testosterone levels drop below normal, the effects can be widespread and noticeable, impacting both physical and mental health.

Recognising the Symptoms of Low Testosterone

The symptoms of low testosterone can vary from person to person, but they often affect several areas of health and quality of life.

1. Persistent Fatigue and Low Energy

One of the first signs people notice is a constant feeling of tiredness. This isn’t just regular tiredness after a busy day; it’s a deep fatigue that doesn’t improve even with adequate rest. Everyday tasks might feel more draining, and you may struggle to keep up with your usual activities.

2. Decreased Interest in Sexual Activity

Testosterone is closely tied to sexual health, so a drop in levels often results in reduced libido. For men, this might also include difficulty achieving or maintaining erections. For both men and women, this lack of interest in intimacy can take a toll on relationships and self-esteem.

3. Mood Changes and Emotional Shifts

Testosterone has a direct impact on mood-regulating chemicals in the brain, like serotonin. When levels drop, it’s common to experience mood swings, increased irritability, or feelings of depression. Some individuals report a sense of apathy or lack of motivation that affects their daily life.

4. Loss of Muscle Mass and Strength

Testosterone helps build and maintain muscle, so low levels can lead to muscle loss. Over time, you might notice a decrease in physical strength, making activities like lifting objects or exercising more difficult.

5. Increase in Body Fat

Low testosterone can also affect how your body stores fat. Many people with low T notice an increase in fat, particularly around the abdomen. In men, this may sometimes lead to a condition called gynecomastia, or the development of enlarged breast tissue.

6. Difficulty with Focus and Memory

A common but less obvious symptom of low testosterone is cognitive changes, often described as "brain fog." You might struggle to concentrate, forget things more easily, or feel mentally sluggish, making tasks that require focus more challenging.

7. Weakening Bones

Testosterone is crucial for maintaining bone density. With lower levels, bones can become weaker and more prone to fractures. This risk is particularly concerning for older individuals, where bone health is already a natural concern.

8. Poor Sleep Quality

Low testosterone can disrupt sleep, leading to insomnia or irregular sleep patterns. This creates a frustrating cycle where poor sleep worsens fatigue, which is already a symptom of low T.

9. Hair Loss

Since testosterone helps regulate hair production, reduced levels can lead to thinning hair or hair loss, not just on the scalp but on the face and body as well.

10. Low Red Blood Cell Production

Testosterone helps with the production of red blood cells. A deficiency can lead to anaemia, resulting in symptoms like weakness, fatigue, and shortness of breath.

Causes of Low Testosterone

There are many reasons why testosterone levels might drop. One of the most common factors is ageing. After the age of 30, testosterone levels in men naturally decline by about 1% per year.

Other causes include chronic illnesses such as diabetes, obesity, and kidney disease. Sleep apnoea and lifestyle factors, like poor diet, excessive alcohol consumption, and lack of exercise, can also play a role. Certain medications, particularly opioids and corticosteroids, may suppress testosterone production. Injuries to the testes or medical treatments like chemotherapy and radiation can also have a significant impact.

How Is Low Testosterone Diagnosed?

If you suspect low testosterone, the first step is to consult a healthcare professional. A doctor will review your symptoms and may order blood tests to measure your testosterone levels. These tests are usually done in the morning when testosterone is naturally at its highest.

Sometimes, additional tests may be required to rule out underlying health conditions, such as thyroid problems or issues with the pituitary gland, which also regulates hormones.

Treatment Options for Low Testosterone

The right treatment depends on the cause and severity of your low testosterone. Common approaches include:

Testosterone Replacement Therapy (TRT)

TRT is a popular treatment that provides testosterone through gels, patches, injections, or implants. It can improve many symptoms, such as fatigue, low libido, and muscle loss. However, TRT isn’t suitable for everyone and comes with potential side effects, so it’s essential to discuss the risks and benefits with your doctor.

Lifestyle Changes

Simple lifestyle changes can make a big difference. Regular exercise, especially strength training and high-intensity interval training (HIIT), has been shown to boost testosterone levels naturally. Eating a healthy diet rich in proteins, healthy fats, and vitamins, such as D and B, can also support hormone health. Reducing stress and getting quality sleep are equally important.

Addressing Underlying Conditions

If low testosterone is caused by a health issue like obesity or diabetes, treating that condition can often help restore hormone levels.

Natural Supplements

Certain supplements, like zinc, magnesium, and ashwagandha, may help support testosterone production. However, it’s important to use these under medical supervision to avoid unwanted side effects.

Do Women Experience Low Testosterone?

Yes, women can also suffer from low testosterone, though it often goes unrecognised. For women, low testosterone can cause symptoms like reduced libido, fatigue, muscle weakness, and mood changes. While testosterone replacement therapy is sometimes used, it must be carefully managed due to the potential for side effects.

How to Prevent Low Testosterone

While you can’t stop the natural decline in testosterone that comes with age, there are ways to slow it down and maintain healthy levels:

• Stay Active: Regular exercise helps stimulate testosterone production and maintain muscle mass.

• Eat Well: Focus on foods that support hormone health, including those rich in zinc, magnesium, and healthy fats.

• Get Enough Sleep: Poor sleep can significantly lower testosterone levels, so aim for 7–9 hours of quality sleep each night.

• Reduce Stress: High stress raises cortisol, which can interfere with testosterone production. Activities like yoga or meditation can help.

• Limit Alcohol and Quit Smoking: These habits can negatively impact testosterone and overall health.

When Should You See a Doctor?

If you’re experiencing symptoms like fatigue, mood swings, or reduced libido that are interfering with your daily life, it’s important to seek medical advice. Early detection and treatment can improve your quality of life and help prevent complications like osteoporosis or heart disease.

Taking Steps to Improve Testosterone Levels

Low testosterone can significantly affect your physical, emotional, and mental well-being. Recognising the symptoms early is the first step towards finding effective solutions.

Whether it’s through medical treatments, lifestyle changes, or a combination of both, there are many ways to address low testosterone and regain your energy and vitality. If you’ve been wondering, “What are the symptoms of low testosterone?” now you know the signs to watch for and the steps you can take to feel better.
