Reduced amounts of melatonin may also play a role in the development of irregular menstrual cycles. Studies are limited and often dated, so newer research is needed. The size of your pineal gland may indicate your risk for certain mood disorders. One study suggests that a lower pineal gland volume may increase your risk of developing schizophrenia and other mood disorders.
More research is needed to better understand the effect of pineal gland volume on mood disorders. Some research suggests that there may be a connection between impaired pineal gland function and cancer risk. A recent study on rats found evidence that lowering pineal gland function through overexposure to light led to cellular damage and increased risk for colon cancer.
Another study found evidence that, when used with traditional treatments, melatonin may improve the outlook for people with cancer. This may be especially true in people with more advanced tumors. More research is needed to determine how melatonin affects the production and blocking of tumors. If the pineal gland is impaired, it can lead to a hormone imbalance, which can affect other systems in your body. For example, sleep patterns are often disrupted if the pineal gland is impaired.
This can show up in disorders such as jet lag and insomnia. Additionally, because melatonin interacts with female hormones, complications may affect the menstrual cycle and fertility. The pineal gland is located near many other important structures, and it interacts heavily with blood and other fluids.
If you develop a pineal gland tumor, it may affect many other things in your body. Some early symptoms of a tumor include:. Talk to your doctor if you have a sleep disorder, or if you want to know more about taking melatonin supplements.
We know melatonin plays a role in setting sleep patterns with day-night cycles. Other research suggests that it helps in other ways, such as in regulating the menstrual cycle. Melatonin supplements may be helpful in managing sleep disorders, such as jet lag, and in helping you to fall asleep. Remember to speak with your doctor before using melatonin, especially if you take certain drugs.
Go to sleep earlier. Aim for hours of sleep each night. If you know it takes you a while to fall asleep, start winding down earlier, and get into bed before you want to fall asleep. Consider setting an alarm to remind you to get ready for bed by a certain time. Avoid the snooze button. Try to avoid using the snooze button on your alarm. Sleep between snoozes is of lower quality. Instead, set your alarm for the time you need to get out of bed.
Exercise regularly at the right time. Exercising regularly helps reduce anxiety and improves sleep quality. Even a minute walk at a brisk pace can make a difference.
Changes in melatonin might explain this phenomenon. An older study of people with impaired pineal glands found that damage to this gland is associated with declines in the sense of direction. The pineal gland may accumulate calcium deposits. These deposits are normal in healthy individuals, but excessive calcification can prevent the pineal gland from functioning properly.
Because the pineal gland is closely associated with the hypothalamus, problems with the hypothalamus — including cancer , growths, or hormonal issues — can cause pineal gland dysfunction. Pineal gland tumors are rare but can also alter pineal function. The most prominent symptom of pineal gland dysfunction is a change in circadian rhythms.
This might mean sleeping too much or too little, feeling active and restless in the middle of the night, or feeling sleepy at unusual times. The pineal gland is indispensable to a process most people take for granted: maintaining a consistent schedule from day to day. Without it, the body would struggle to sleep and wake at the same time, and might not know how to respond to changes in light levels properly.
More research may reveal additional pineal gland functions and determine how light and melatonin affect everyday health. A hypophysectomy is a procedure to remove the pituitary gland because there is a benign or malignant tumor present. This is a difficult procedure that….

There is considerable research that shows that without the pineal gland and its secretion of melatonin, animals are unable to adapt physiologically to seasonal changes.
It is not unusual to see pineal cysts on magnetic resonance imaging MRI scans. However, on rare occasions, tumours of the pineal gland are found. There are some extremely rare reports of precocious puberty early puberty in individuals with pineal gland cysts or tumours. It is not clear whether these changes in puberty are caused by melatonin or some other hormone, such as human chorionic gonadotrophin , which is reported to be released by some pineal tumours.
Otherwise, there are no known diseases associated with over or underactivity of the pineal gland. About Contact Events News. Search Search. You and Your Hormones. Students Teachers Patients Browse. Human body.
