No one knows why, but today, the rate of asthma in children is growing. According to WHO, every year more and more children are being diagnosed with asthma worldwide. In the US, more than 10% -12% of children develop childhood asthma annually, and this percentage is gradually increasing for some unknown reasons.

There is no known cause of asthma, but several factors may play a part to lead you to the disease. Researchers have identified quite a few risk factors for developing childhood asthma. These include nasal allergies or hay fever, frequent respiratory infections, low birth weight, being exposed to tobacco smoke before and after birth, black or Puerto-Rican ethnicity, and being raised in a low-income environment.

Although the exact cause of Asthma is still unknown, but several recent studies suggested that many factors play a part in the development of this condition. Recently, a study done by Dr. Richard Locksley and his team suspected that asthma might be caused a compound named ‘Chitin’ (pronounced KI-tin), a common compound found in most of the highly allergenic organisms. Yet, the team is still researching on the compound to find out the root causes of asthma.


Factors and Possible Causes of AsthmaGenetic FactorMany scientists believe that patient who has a parental history of asthma or other allergic conditions is more likely to inherit the disease. This inherited tendency to grow allergic conditions is known as atopic conditions. Patients with a family history of atopic conditions or asthma are more reactive to allergens as compared to normal persons. You need to know that almost all asthmatics develop allergic c…

The digestive system is the main functional system in the human body. It helps to provide essential energy and nutrients in our body by performing ADME (Absorption, Distribution, Metabolism and Excretion) of the foods, drinks or anything we ingest. In other words, the digestive system is a series of responsible organs that help to produce energy and digest foods in a human body.


Organs of the Human Digestive SystemSeveral functional and auxiliary organs are involved in the digestion of foods. Organs of the upper and lower gastrointestinal tract are directly involved in the digestion process.
Upper Gastrointestinal Tract:Mouth, teeth, tongue, pharynx, esophagus, and stomach.Lower Gastrointestinal Tract:Small intestine, large intestine, and anus. Liver, pancreas and gall bladder are also part of the digestive system, but as they indirectly involve in digestion, they're considered as auxiliary organs. How the Digestive System Works? When food enters into the mouth, it mixes with saliva…
