Poor Gut Health Will Mess With This Hormone

As a physician and gut health specialist, I’ve written a lot about the hormone fluctuations and disorders that occur in women due to disordered gut health. And what I've noticed over the years is this: Men often get left out of the conversation completely.

Fatigue, mental fog, lack of motivation, depression, and loss of a sexual appetite are just a few of the symptoms that should send you to the doctor asking to have your testosterone levels checked. As much as they may feel like the consequences of aging, these symptoms aren’t the mandatory repercussions of growing older. They could actually be resulting from low testosterone.

As men age, testosterone levels drop 1 to 2 percent3 every year, and deficiencies affect about 30 percent of men ages 40 to 79 years old. Certain conditions including obesity, diabetes, and hypertension can worsen testosterone deficiency4. As with any hormone, the key is balance. Researchers have surprisingly found that when testosterone levels decline1 in men, so does estrogen, since your body converts some free testosterone to estradiol (the most active form of estrogen in the body, which is produced by both men and women).

When I help patients minimize toxins, balance their lifestyle, and clean up their diet, they find a secondary added benefit: Testosterone levels are boosted! A nutrient-dense diet rich in healthy fats (like a ketogenic diet) coupled with intermittent fasting is a great way to lose weight, improve gut health, and optimize testosterone levels. I also recommend drinking filtered water, avoiding hormone disrupters such as bisphenol-A (or BPA), and taking a high-quality probiotic as research shows probiotic supplementation can even help prevent low testosterone2 in men. In fact, there are a few supplements that have been shown to boost testosterone.

Yet even when some men do everything correctly—eat clean, do intermittent fasting, exercise, sleep, minimize toxin exposure, meditate, and control stress levels—they might still need and feel best with testosterone replacement therapy (TRT). Some researchers argue we lack studies supporting its long-term safety, and overall studies are varied, but for many men TRT can help restore testosterone6 and regain this hormone’s many benefits.

But for most of us, diet and lifestyle go a long way, and they should always be the first steps toward regaining hormone balance.
