Gastric acid is a digestive fluid, formed in the
stomach. It has a
pH of 1.5 to 3.5 and is composed of
hydrochloric acid (HCl) (around 0.5%, or 5000
parts per million) as high as 0.1 M,
[1] and large quantities of
potassium chloride (KCl) and
sodium chloride (NaCl). The acid plays a key role in digestion of
proteins, by activating
digestive enzymes, and making ingested proteins unravel so that digestive enzymes break down the long chains of
amino acids.
Gastric acid is produced by cells lining the stomach, which are
coupled to systems to increase acid production when needed. Other cells
in the stomach produce
bicarbonate, a base, to
buffer the fluid, ensuring that it does not become too acidic. These cells also produce
mucus,
which forms a viscous physical barrier to prevent gastric acid from
damaging the stomach. Cells in the beginning of the small intestine, or
duodenum,
further produce large amounts of bicarbonate to completely neutralize
any gastric acid that passes further down into the digestive tract.
The presence of gastric acid in the stomach and its function in digestion was first characterized by
United States Army surgeon
William Beaumont around 1830. Beaumont was able to study the stomach action of fur trapper
Alexis St. Martin due to the latter's gastric
fistula.
What is Excess Stomach Acid?
When we eat food, our body needs to break it down into
usable nutrients and vitamins. The process of this breakdown starts off
in the stomach. The
stomach secretes an acid that is essential in the digestive process, as this acid helps in breaking down the food during digestion.
Usually, protective mechanisms in the stomach and proximal intestine make sure that the acid levels are in balance. However,
when the stomach produces too much acid,
it results in a condition known as Acidity, or APD. Excess gastric
acid is more prevalent in the morning when the stomach is empty.
Excess stomach acid levels can contribute greatly to:
- Heartburn
- Dyspepsia (often described as a feeling of indigestion, fullness, bloating, flatulence or nausea)
- Duodenal ulcer
- Gastric ulcer
- Peptic ulcer
- Non-ulcer dyspepsia
- Acid Reflux
Causes of excess stomach acid:
- Pregnancy
- Eating disorders (e.g. Bulimia)
- Dehydration
- Diabetes
Symptoms of Excess Stomach Acid:
- Hair Loss
- Bad Breath (Halitosis)
- Belching
- Nasal Congestion and Phlegm
- Abdominal Pain
- Throat Pain
Excessive Stomach Acid During Pregnancy
There are a couple reasons why pregnant women suffer
with excessive stomach acid. One of the main reasons is due to raised
hormone levels. When hormones are constantly changing the digestive tract muscles are affected and therefore can result in the way different foods are tolerated. Secondly, a growing baby also crowds the abdomen, pushing acids upwards.
As with many pregnant women, heartburn can be a result of excessive stomach acid.
Pregnancy hormones cause the lower esophageal sphincter to relax which
allows stomach acid to seep back up into the esophagus, causing acid reflux.
Excessive Stomach Acid in Babies and Children
Just like adults babies and children can suffer from excessive stomach acid too. For growing babies, stomach acid is part of normal digestive system growth.
When stomach acid is in excess it can lead to acid reflux in which the
stomach acids start to travel up the esophagus thereby resulting in
"spitting up" or vomiting. Though many babies suffer from reflux symptoms it can be painful for the child and troubling to parents.
Older children who suffer from excess stomach acid often complain of an upset stomach. Frequently, children who overeat unhealthy foods such as cookies or candy develop excessive stomach acid. Alternatively, nervousness or anxiousness can create tummy acid.
Help for Excess Stomach Acid
Natural Remedies
Many herbal and homeopathic remedies have been formulated with specific ingredients to assist the body in keeping excess gastric acid levels in balance. Mentha Piperita is an herb from the mint family that has been used for many hundreds of years for relief of indigestion, nausea and heartburn.
Its calmative properties relax the muscles of the digestive tract and
stimulate the flow of natural digestive juices and bile, thereby
assisting healthy digestion.
Nat.Sulph. Is a tissue salt and is known as the 'cell cleanser.' This tissue salt regulates body fluids and helps to promote healthy functioning of the digestive system, thereby preventing nausea as well as the bitter taste in the mouth often associated with acid reflux and regurgitation.
How to Avoid Excess Stomach Acid
- Try to identify foods that contribute to excess stomach acid. Foods that are spicy, salty and acidic should be avoided.
- Smoking and alcohol consumption should be stopped to keep stomach acid levels in the stomach and esophagus in harmony.
- Avoiding stress and moderating your lifestyle to include relaxing techniques can go a long way to prevent excess stomach acid and ulcers, particularly if you are a nervous and emotional person or involved in a high-stress job.
- Avoid non-steroidal anti-inflammatory drugs (NSAIDs). These drugs may predispose a person to excess stomach acid.
- Try to eat regular meals and follow a healthy diet.
- Take extra care when lifting weights, as this puts the abdominal area under added strain and may result in digestion problems.
- If you have a bout of excess stomach acid, try having an
organic glass of fat-free or low-fat milk to help normalize the pH in
your stomach.
