You might not realize it, but stress in your gut can cause cause your T levels to drop. It can lead to weight can fatigue and a lost sex drive. How is that possible?
Easy. Stress in the gut can cause cortisol to rise. Cortisol is basically a stress hormone. When cortisol is up, and when stress is up, testosterone can drop, especially over the long term. So guys with chronic stomach problems tend to experience the symptoms of lower testosterone in men- fatigue, weight gain and loss of sex drive.
