Many hormones at some point have a connection with the gut, meaning it’s either created there, arranged there, regulated by it, secreted from there, etc.
What is the GUT?
The “gut” consists of the entire digestive tract from the mouth all the way to the colon, containing anywhere from 10-100 trillion symbiotic microbial cells. These microbes are referred to as the gut microbiome
The human body has more bacteria cells than any other type of cell. Most of these microbes (bacteria) reside in the gut.
What happens with too many bad bacteria?
This causes hormonal disturbances, inflammation, and other processes take place which can lead to health issues.
Examples of hormones affected by the gut.
1. Research shows that the microbiome plays a big role in estrogen regulation. It states that poor gut health increases risk of estrogen related diseases such as PCOS, endometriosis, and more. (1)
2. 95% of serotonin is produced and stored in the gut. This is why people with unhealthy microbiomes could have depression and anxiety.(2)
3. An imbalanced gut microbiome can be one of the causes of a low performing thyroid, or hypothyroidism. Symptoms of this include chronic fatigue, weight gain, and hair loss. (3)
4. Insulin, in part, can be regulated by Lactobacillus reuteri which is stored in the gut. With inflammation being a key symptom of an imbalanced microbiome, a deficiency of this beneficial flora makes it even worse.(4)
5. Gut health also influences healthy cholesterol levels. These are precursors to maintaining balance of progesterone and estrogen.(5)
6. Certain cells in the gut synthesize and secrete some hormones which have roles in key processes like insulin sensitivity, glucose tolerance, fat storage, and appetite. (6)
Artificial sweeteners and the gut-
1️⃣”Artificial sweeteners change the gut bacteria which may lead to weight gain and risk of type 2 diabetes.”(7)
2️⃣They have been shown to eliminate good bacteria in your gut. In one study, rats were given sucralose for 12 weeks and their good bacteria decreased by 47-80% and after another 12 weeks off of sucralose the gut had not repaired itself. (8)
