Introduction
One of the most important facets of a person’s existence is their health. Being unable to carry out usual day-to-day tasks due to a lack of wellbeing or fitness can hinder you from living a normal life.
Why Do We Fall Ill?
We may become ill for a variety of causes, which are described below:
An illness is an irregular condition that affects an individual. There are also psychiatric disorders characterized by a pathological mechanism and a set of symptoms.
Any illness has a cause. However, some illnesses are impossible to detect due to their perplexing signs. Autoimmune, viral, cancerous, digestive, sexually transmitted, and other disorders are possible. Antibiotics, other drugs, and surgical procedures may all be used to treat them.
Antibiotics are components that stop bacteria from using their biochemical mechanisms to induce disease. However, these are ineffective against viral infections since viruses depend on the host’s biochemical pathways.
When we feel something is wrong in our organs or organ systems, it could mean that we are ill or have a disorder. Our body’s natural working is disturbed as a result of this. When we have an illness, our bodies send us clues. These are called symptoms. Headache, cold, cough and nausea are some of the typical symptoms.
There are two groups of diseases:
Acute illnesses
These are those that last for only a limited duration, such as a few days or a few weeks. Chickenpox, typhoid and the common cold are a few examples of acute illness.
Chronic illnesses
These are those that last for an extended period, or sometimes for the rest of a person’s life? Cancer and HIV are a few examples.
Diseases may have a variety of immediate causes:
Here are a few suggestions for leading a safe and disease-free life:
When we get ill, we follow a set of procedures to cure the illness. An illness may be treated in one of two ways:
Reduce the disease’s effects: Medicines are provided to alleviate discomfort or lower the temperature. To put it another way, symptomatic therapy may lessen the severity of a disease, but it may not completely cure it. Since certain illnesses, such as the common cold, do not have a remedy, managing the effects will relieve the pain or infection to some degree.
Kill the disease: Using antibiotics that can destroy bacteria and kill the disease’s source. Each microbe goes through a unique biochemical life process that aids in its survival. Certain medications that block these biochemical pathways may aid in the killing of the disease-causing microorganism. Antibiotics are useful in this situation.
In this chapter, we learned about the reasons behind falling ill. We learned about different types of diseases. We gathered knowledge on how to treat and prevent diseases.
1. Why do we fall ill class 9 Ncert?
Immediate and contributory factors are the two primary causes of illness. The species that invade our bodies and trigger illness are the immediate cause. Viruses, protozoa, and viruses, for example. Contributory causes: These are the reasons that allow these species to invade our bodies—for example, contaminated food or water.
2. Why do we fall ill principles of treatment?
To lessen the impact of illness, we provide care that alleviates symptoms. For example, we may use pain relievers, anti-inflammatory drugs and bed rest to alleviate fever.
3. What is the major drawback of principles of treatment?
The only disadvantage of the treatment theory is that treatment can vary where specific signs and symptoms are not present, resulting in a variety of side effects.
4. What is the first principle of treatment?
The ideals of treatment are to lessen the symptoms, thereby reducing the effects of the disease.
5. What are the principles of the prevention of diseases?
