If your digestive health is sluggish or failing, it is likely highlighted by undigested food appearing in your stools, and bowel motions swinging between constipation and diarrhoea. Chronic fatigue, irritability, acid reflux, bloating, and brain fog are also common symptoms.

Most researchers believe that up to 90 percent of all diseases and health issues begin in the gastrointestinal tract. The lining of your gastrointestinal tract is susceptible to many forms of attack, both bacterial and viral. Other factors can lead to damage of this lining, including long-term use of broad-spectrum antibiotics, excessive consumption of alcohol, eating large amounts of refined foods, and overuse of pharmaceutical drugs.

You may also not take into consideration things that are invisible, like stress. Whether perceived or real, your body can't tell the difference, and you go into fight or flight mode. This perceived stress causes blood to leave your gastrointestinal lining, to be sent to your arms and legs to fight with someone or to run away.
