The digestive system is process and continuous and systematic action which involves breaking large food particle and molecules into small particles and molecules in order to make them absorbable is called digestive system, Digestion occurs in GI (gastrointestinal) tract or alimentary canal which start from the mouth and ends to the anus. Digestion is of two kinds.
If food particles are mechanically broken or when large food particles are broken into small particles without any change in their chemical composition is called Mechanical digestion. If the digestion occurs chemically or when large molecules are broken into its constituent small molecules is called Chemical digestion.
Why do we need a digestive system?
When we ingest food whether it is a vegetable, meat products or something else mostly the food consists of large molecules and particles. If these particles aren’t broken, they couldn’t be absorbed from the wall of the intestines. So, there should be a system that would be able to break such giant molecules and that is the digestive system. It not only digests the food particles but also kills the bacteria and other microorganisms.
Sometimes this system shows disorders or problems in certain positions of the GI tract. We will talk about some minor digestive problems in this article.
It is the body’s self-defense mechanism against infectious and contaminated food. Sometimes due to certain infection or food poisoning in the stomach, the ingested food is expelled out through mouth forcefully this condition is called as vomiting. In some conditions, it becomes very serious that even water after drinking is expelled out. Vomiting for a long time causes dehydration. The condition of one about or feeling to vomit is medically termed as nausea. It is always not necessary for anyone having nausea to vomit. In vomiting, the contaminated food is expelled from mouth forcefully because of antiperistalsis. After vomiting, the body feels better and relaxed.
Always vomiting occurs after nausea. Abdominal pain, lightheadedness, and loss of appetite are the most common symptoms.
Usually, after vomiting, one feels better but one can be dehydrated after continuous vomiting. For this purpose, medicines are prescribed by your doctor to stop the vomiting process and for getting rid of dehydration drips are used which are connected to your vein or ORS after stopping vomiting.
It is also the body’s defense mechanism against infectious and contaminated food. When your food gets infected by certain microorganisms especially bacteria in your intestines. Then due to the defense mechanism of your body, the contaminated food is not digested and also not absorbed by the small and large intestines and expelled through the anus. As water absorption is stopped therefore feces contain a large amount of water.
In severe cases of diarrhea since no water, minerals, and food is absorbed therefore dehydration occurs.
The symptoms of diarrhea include severe pain in your abdomen (stomach), dehydration and a large amount of water in feces (stools), weakness, headache and frequent use of the toilet.
After the ejaculation of contaminated food, the digestive system gets well soon within a couple of hours or a day. Use ORS, for getting rid of dehydration. If it continues for more than some days. Your doctor will recommend you medicines for stopping diarrhea.
When the undigested and rejected materials from your food enter to your rectum (position of GI tract which starts after ending of Large Intestine) a signal of using the toilet is sent to your brain. If you didn’t get rid of it the walls of large intestine absorb more water from it which results in constipation. It also occurs when food material moves (movement occurs due to peristalsis) less slowly from your GI tract more water would be absorbed causing in painful and forceful excretion of the feces (bowel).
The symptoms include pain in the lower side of your abdomen, heaviness, pain on the lower side of your abdomen on movement and forceful ejaculation of feces.
If you want to get rid of constipation follow following steps,
- Use the excess amount of water to soften the bowel.
- Use fibers and vegetables in your diet as they enhance the peristalsis process.
- Seat on soft cushions, etc.
- Stop the excessive use of meats as they stop and slow down the peristalsis.
Food poisoning-digestive system
It is the disease associated with the ingestion of contaminated and toxified food. The contaminated food contains several microorganisms, that can disturb digestion in any position of your GI tract food poisoning may occur by eating many heavy verities foods at the same time. food can be contaminated due to uncareful handling and cooking.
Symptoms of food poisoning may start after a few hours of ingesting contaminated food. The symptoms include nausea, vomiting, diarrhea, and loss of appetite.
Often food poisoning doesn’t need any special treatment. After the excretion of contaminated food, the patient will feel better. However, some serious cases may be shown to the doctor.
Acid reflux-digestive system
Acid reflux is also known as GERD (gastroesophageal reflux disease). At the end of the esophagus, there is a valve that allows the food material from the esophagus to the stomach named. The valve is called a cardiac sphincter. Sometimes the sphincter cannot close properly after the entrance of food in the stomach. This causes the small amount of acid to enter into your esophagus causing pain in your chest for a small period. If this process occurs frequently then you have acid reflux disorder. Symptoms include frequent chest burning and heartburn.
If you have any of the above symptoms, you can visit your doctor immediately. He will prescribe you certain medicines depending upon the intensity and amount of the burning.
