Well, firstly, you might have realised that your stomach isn’t functioning the way it used to. You might be more prone to bouts of diarrhea, constipation, bloating, nausea, and heartburn. This discomfort and irritation of the bowels may be due to poor digestion and absorption of the carbs you consumed. This points to how there is an imbalance in the microbiome, and the bad bacteria is overwhelming your gut and preventing proper breakdown of the food you consume.
If you start to have cravings for sweet food and sugar, there’s a possibility that the bacteria in your gut is imbalanced. This happens when antibiotics wipes out all the good bacteria in your gut, allowing for an overgrowth of yeast, which causes you to crave more sugar.
3. Drastic weight changes
If you gain or lose an exaggerated amount of weight, it could be because of a condition known as the small intestine bacterial overgrowth(SIBO). There are a few types of gut bacteria that contribute to weight loss, and not in a good way. They interfere with your absorption of vitamins, minerals and fats, causing you to lose out on certain necessary supplements needed for your body to function normally. There are also some bacteria that cause you to gain more weight by taking in more calories from food.
As mentioned above, good bacteria in your gut helps manufacture serotonin, which is a neurotransmitter that affects mood, social behavior, sleep, appetite, memory, and even libido. An imbalance in gut bacteria can cause less serotonin to be produced, which has an adverse impact on your mood, as most of the serotonin produced in your body is from the gut. This thus possibly leads to the onset of depression.
Another effect of the lack of serotonin would be the inability to get proper rest, or to even sleep in the first place. That’s why watching what you eat can help improve your sleep.
6. Skin rashes and eczema
Your gut health also has direct connections to your skin. This is caused by the widening of the pores of the digestive tract when your gut is filled with bad bacteria. This allows toxins to leak through into your blood system, which causes your body to attack the invaders, leading to inflammation of the skin.
