When it comes to men's health, testosterone is king. It helps with muscle mass and strength, bone density, fat distribution, sex drive, energy levels and the production of red blood cells. (1)

The hormone testosterone is most commonly associated with male sex characteristics, but it's also essential for overall health. (2) If your testosterone level is low, then you may experience the 7 symptoms listed below.

1) Fatigue and Decreased Energy Levels

Depending on your lifestyle, fatigue can be a normal part of life. But when you are constantly tired and lacking energy, even after a good night's sleep, it may be a sign of low testosterone. (3)

2) Decreased Sex Drive

If you're not interested in sex anymore and lack the desire to get intimate with your partner, this could mean that your testosterone levels are too low. When testosterone levels drop, so does your libido. (4)

3) Depression

Low testosterone levels have been linked to feelings of sadness or hopelessness. This feeling can quickly become debilitating, which often leads to an inability to focus and concentrate. This can further contribute to feelings of isolation and loneliness. If these negative feelings keep going unchecked for long periods, they can lead to depression. (5)

4) Changes in Body Shape 

Low testosterone can cause weight gain around the stomach area (Belly Fat) (6). This can make you look like you've gained 30 pounds.  Body fat contains an enzyme called aromatase, which converts testosterone to estrogen, a female hormone. When estrogen is high, testosterone levels are low, which can lead to belly fat. (7)

5) Decrease in Muscle Mass 

One of the most common signs of low testosterone is a decrease in muscle mass. Testosterone helps with protein synthesis, which is essential for building muscle tissue. Without enough testosterone, your muscles will start to break down over time, which can lead to weakness and decreased strength. (8)

6) Erectile Dysfunction 

In addition to a decrease in sex drive, when you have low testosterone levels, it can be difficult or impossible for you to achieve or maintain an erection. (9)

 If this happens regularly, it may be time to see your doctor and discuss the possibility of taking supplemental testosterone. (10)

7) Sudden Hair Loss 

One of the most noticeable signs of low testosterone is a sudden receding of the hairline just above the forehead. Although this may be due to aging, it is also a common sign of low testosterone. (11)

8) (Bonus) Mood Swings 

When testosterone level drops, it can cause your mood to change as well. (12) You may suddenly become irritable, have mood swings or even get angry quickly without any warning. This can cause problems in all areas of your life, such as putting a strain on relationships with friends and family members, work relationships and even making it difficult to get along with co-workers. (13)

Conclusion:

Low testosterone levels can cause various mental and physical problems, including low sex drive, weight gain around the stomach area, changes in body shape, depression, decreased muscle mass, erectile dysfunction and sudden hair loss. 14

If you have been experiencing any of these symptoms for more than a few weeks, it may be time to talk to your doctor.
