Lactose deficiency & what are the symptoms of lactose intolerance?

Lactose deficiency  

Lactose intolerance or lactase deficiency is a very common problem. The sugar found in milk is called lactose. Lactase is an enzyme that hydrolyzes the lactose disaccharide into glucose and galactose on the brush boundary. 

Lactose intolerance occurs when your bowel does not produce enough enzyme (lactose) to digest sugar from milk (lactose), a deficiency of an enzyme called lactose. 

 

Lactose intolerance by country

The concentration of lactase enzyme levels is elevated at birth but decreases progressively through childhood and adolescence and into adulthood in most people with non-European ancestry. While in the United States, about 50 million people have partial or full lactose intolerance.

As many as 90% of Asian Americans, 70% of African Americans, 95 of Native Americans, 50% of Mexican Americans, and 609% of Jewish Americans are lactose intolerant compared with 25% of white adults. 

Lactose deficiency symptoms  

The most common symptoms of stomach pain and bloating arise when bacteria in the colon ferment lactose that could not be digested. By can the amount of water in the colon, 

 Many individuals can get diarrhoea, bloating, stomach pain, flatulence, headache, or vomiting after drinking milk or consuming cured or consuming other dairy products, With higher lactose ingestions, osmotic diarrhoea will result. 

Isolated lactase reduction does not result in any additional symptoms of weight loss or malabsorption. 

Lactose fermentation in the colon can lead to an increase in gas. Patients have great variability in clinical symptom,  depending on both the severity of lactase deficiency the amount of lactose ingested. 

There is a tendency for all lactose-intolerant and lactose-tolerant people to incorrectly assign a number of abdominal symptoms to lactose intolerance because of the unspecific nature of these symptoms.

Most patients with lactose intolerance. May drink one to two 8-oz glasses of milk daily without symptoms if consumed at broad intervals between meals, even though rare patients are almost completely intolerant.

If these findings are present, other gastrointestinal disorders should be present. Specimens of diarrhoea show an enhanced osmotic difference and a pH of < 6.0. Constipation can also be an indication that lactose isn't fully digested.

Lactose intolerance causes

The reason for intolerance to the lactose is that our body has enzymes called lactase, If the enzymes are low, our body will not be able to handle lactose in the milk, so we get loose motion, diarrhoea, painful stomach and vomiting. 

As lactose secretion decreases with increasing age, the capacity to digest lactose also decreases. An estimated 70 per cent of adults can not digest lactose properly.

Lactose intolerance effects

Lactase disorder can also occur relative to other gastrointestinal disorders involving the small intestinal mucosa in the proximal area.

That includes Crohn's disease, giardiasis, short bowel syndrome, sprue, bacterial gastroenteritis, and malnutrition. 

Malabsorbed absorbed lactose is fermented by intestinal bacteria, producing gas and organic acids. Unmetabolized lactose and organic acids result in an increased osmotic load of the stool and an obligatory loss of fluid. 

Lactose deficiency labs  

Lactose intolerance breath test, The most widely available test for the diagnosis of lactase deficiency is the hydrogen breath test. After ingestion of50 g of lactose, a rise in breath hydrogen of > 20 P within 90 minutes is a positive test, indicative of bacterial carbohydrate metabolism. 

Most physicians recommend an observational trial on a lactose-free diet for 2 weeks in clinical practice. Resolution of symptoms (bloating, flatulence diarrhoea) is suggestive of lactase deficiency and may be confirmed, if necessary, with a breath hydrogen study.

Lactose intolerance treatment

In patients with isolated lactase deficiency, the aim of therapy is to achieve patient satisfaction.  In patients with isolated lactase deficiency, the aim of therapy is to achieve patient satisfaction.

Patients typically find their medication "threshold" for signs arising at. Milk (12 g / cup), ice-cream (9 g / cup), and cottage cheese (8 g / cup) are rich in lactose. Older cheeses have lesser lactose (0.5 g / oz).

Unpasteurized yoghurt contains bacteria that produce lactase and is generally well tolerated. By extending dairy product intake in amounts of < 12 g lactose (one cup of milk) during the day, most patients may take dairy products without symptoms and do not require lactase supplements. 

Most food markets provide milk that has been pre-treated with lactase, rendering it 70-100% lactose-free. For non-prescription formulations, lactase enzyme substitute is commercially viable.

Milk products can take caplets or drops of lactase, enhancing lactose absorption and reducing symptoms. Depending on the degree of lactose intolerance, the number of caplets ingested.

There may be an increased risk of osteoporosis in patients who choose to restrict or eliminate milk products. Calcium Supplementation (calcium carbonate 500 mg orally two to three times daily) is recommended for susceptible patients.

Lactose intolerance people can easily use coconut milk, almond milk, and soy milk because these milk are lactose-free, cholesterol-free and sugar-free, these also contain plenty of calcium.
