What is the GI system
Involved in food intake, processing and excretion
Mouth
Salivary glands
Oesophagus
Stomach
LI and SI
Anus
What does the mouth do in GI
entrance to the digestive tract.
The teeth break down food.
Saliva begins carbohydrate digestion
Digestion in the mouth is minimal; no absorption of
nutrients occurs.
What does the oesophagus do in GI
During swallowing, food is prevented from entering the wrong passageways.
The pharyn-goe-sophageal sphincter prevents air from entering the digestive tract.
What does stomach do in GI
The stomach stores food and begins protein digestion.
What does the S.I do in GI
break down food, absorb nutrients needed for the body into blood, and get rid of the unnecessary components
What does the L.I do in GI
The large intestine is primarily a drying and storage organ.
Connected to small intestine at one end and anus at the other.
4 parts: cecum, colon, rectum and anal canal
What does the anus do in GI
Is the last part of the digestive system
consist of pelvic floor muscles and 2 anal sphincters.
Job is to detect rectal contents, gas, liquid or solid and control if a still should be excreted or not.
What is indigestion/heartbburn
Indigestion : Also called functional dyspepsia
Pain experienced in chest caused by overproduction of acid that the stomach produces when we eat. The over production leads to irritation and inflammation of stomach lining
Heartburn : also called GORD and reflux
Caused by food and stomach acid escaping the stomach and returning up the oesophagus. Can occur if there is weakness in the sphincter between the oesophagus and stomach.

- Smoking.
- Certain medicines.
- Being overweight.
- Being pregnant.
- Stress.
Treatments for indigestion/heartburn . Mechanism and active ingredient :
Antacids : neutralise stomach acid - sodium bicarbonate or Mg salts
Alginates : create a mechanical barrier - sodium alginates
H2-antagonists : bind to histamine receptors interfere with gastric acid production and secretion - famotadine
Proton pump inhibitors : inhibit gastric acid secretion - pantoprazole
Formulations and points of interests for antacids
Liquids and chewable tablets
Fast acting but also short acting so might need repeat doses. Some have high sodium content and can cause diarrhoea
Formulations and points of interests for alginates
Liquids and tablets
1st line treatment for GERD. Safe for children and pregnancy. After meals. Can cause diarrhoea and nausea.
Formulations and points of interests for H2-antagonists
Tablets
Stop smoking whilst taking. Reduce alcohol intake. Often taken with 1st meal of the day.
Formulations and points of interests for proton pump inhibitors
Tablets and IV
Once a day in the morning. Can cause headaches and diarrhoea. Avoid spicy foods and cut down on caffeine and alcohol.
