There’s no doubt about it – hormones are powerful. You feel them at work every moment of the day, from when you wake up in the morning until you go to bed at night. While you can certainly feel their impact, you don’t really always have clear evidence that they are out of balance.

There are some well-known signs of imbalance, but many of the signs of hormone trouble aren’t obvious at all. You may even be experiencing some of them right now, but attribute them to other things in life, like stress, bad sleep, or overworking.

Here are some of the lesser known signs of hormone imbalance you should be on the lookout for:

Chronic fatigue: People often ignore fatigue, especially when they work a lot or are stretched too thin with family obligations. Chronic fatigue, however, can actually be a sign of other health issues, including hormone imbalance. If you’re always tired, never feel rested, and seem unable to break the fatigue cycle, hormones might be to blame.

Sleep trouble: Hormones regulate many aspects of your life, including your sleep and wake cycles. When your hormones aren’t in balance, you can experience a range of sleep disturbances, like having a hard time getting to sleep, having a hard time staying asleep, or even periods of insomnia. Struggling with sleep problems on a regular basis might point to a hormone problem.

Memory issues: Hormone imbalances can impact your memory and cause a lot of other issues as well, like an inability to focus, lack of concentration, and brain fog. These symptoms are had to ignore, but they often get blamed on being stressed out or working too much. If such symptoms are new, or if you’re really not more stressed than normal, hormones might actually be to blame.

Frequent headaches: Headaches are a common problem and have many root causes, from mechanical issues in the spine to muscle tension. If you happen to have a change in the frequency of headaches, or have headaches that don’t seem connected to spinal issues or muscle pain, hormones might be at fault.

Hormones play a huge role in our general health and well-being, so when they aren’t at their optimal levels, our sense of well-being declines. The best thing to do is to pay close attention to how you feel, especially if there is a change in your overall health. If you suspect that you have a hormonal imbalance, then you should get your levels checked right away. Not only will this tell you where your current levels are, it will also help your health care provider create the best plan for restoring balance and improving how you feel.
