Anatomy and Physiology: Aromatherapy and the Digestive System

You body gets its energy and nutrients through eating, but the food that you eat is very different to what's used by your cells. Ingested food must go through the process of digestion. There are two stages of digestion: mechanical, which starts in the mouth with chewing and swallowing; and chemical, which involves enzymes breaking down food into soluble substances that can be absorbed into your circulatory system.

When the functions of assimilation (absorption of food) and elimination (excretion of food) are impaired, your body's ability to process nutrients and to get rid of waste is affected. It can cause unpleasant symptoms such as diarrhoea, stomach cramps, constipation and headaches.

Treating the Digestive System

Your digestive system is very sensitive to the rest of your body systems and can be upset not just by what you put into your body but by how you feel and react to things.

Flatulence is the build-up of gas in the stomach and intestinal tract. This excessive wind is released orally or anally. Gas enters the intestine when air is swallowed as you eat or drink or from released gases of digesting foods (beans are often a common culprit).
