Sleep, Hormones and Weight Gain

How Sleep Affects HORMONES

Studies indicate that sleep loss shifts the hormonal balance from hormones that promote fullness (satiety), such as GLP-1, to those that promote hunger, such as ghrelin.

Sleep restriction also increased levels of endocannabinoids, which is known to have appetite-promoting effects. Further studies show that acute sleep loss alters the balance of gut bacteria, which has been widely implicated as key for maintaining a healthy metabolism.

Melatonin and Cortisol

Most people need between 7 and 9 hours each night of good quality sleep.

Too little sleep can trigger a cortisol spike at night and disrupts our nocturnal clock. This stress hormone signals your body to wake up. It is naturally at its highest peak 60 mins from waking in the morning, and declines through the day to the lowest point which should be just before bed.

It works in opposition to melatonin, a hormone that puts us to sleep. Therefore, cortisol will suppress melatonin, and melatonin will suppress cortisol – like a see-saw. If you have a spike of cortisol at night, your melatonin instantly drops, waking you up and making it very hard to drop back to sleep.

Factors that can trigger a cortisol spike at night are many, but here some we commonly see in the clinic:

• Electronic devices used in bed – particularly ‘blue’ light devices such as mobiles, kindles and notebooks.
• Coffee, tea or other caffeinated drinks late in the day or before bed.
• Pain and discomfort in bed.
• Fatty liver, functional issues with detoxification, high toxin load in the body.
• Adrenal imbalances.
• Blood sugar imbalances.
• Eating high sugar foods and too large a meal too soon before bed.

✪ Some of these issues you can fix yourself, but if sleep still eludes you, then a functional screening and treatment approach can help you get to the core of the issue.

Growth Hormone and SLEEP

The pituitary gland secretes growth hormone (GH) where its highest output is in the first hour of sleep. Like waves on a beach, there will be smaller bursts of GH through the night. Therefore, the more you sleep, the more GH produced.

Once in the blood stream, GH stimulates the production of insulin-like growth factor-1 (IGF-1). These two work favourably in our body, with GH involved in fat burning, and IGF-1 involved in muscle growth.

GH is suppressed when the body has elevated levels of Leptin and high blood sugar, so keeping these levels in check is one step involved when balancing your hormones with a functional medicine approach.

When working with body in such a comprehensive way, you can’t guess what is happening between all the hormones. This is because many symptoms can cross over between endocrine functions, so basing treatment on symptoms alone is a bit like throwing a dart blind-folded. After being spun around in a circle 10 times.

That’s why we specialise in functional testing – this is a panel of pathology tests that are done with serum, saliva and urine samples to give you specific answers regarding your hormones, nutrient deficiencies or excesses, detoxification status, and methylation status.
