Environmental factors play a quintessential role in affecting our health. Fresh air, fresh food and fresh water, not only strengthen our body and mind but also make our life worth living. Contrary to this bad environment hampers the quality of life. This is the main reason why people from hill stations or the countryside seem to be healthier than those living in polluted urban cities. Following are the environmental factors that affect your health:

Polluted air

The health effects of polluted air are several. Not many people know that one-third of the deaths are caused because of strokes, lung cancer and heart failure. Air pollution is the chief reason behind these chronic ailments. The other life-threatening diseases caused by polluted air is- asthma or bronchitis. Smoke from machines, vehicles outside, and stoves, the burning of fuels inside can cause breathing problems and wheezing. 

Dirty environment

A dirty environment often leads to the breeding of insects and bacteria that become carriers of life-threatening diseases such as dengue, typhoid, diphtheria, malaria, and so on. Most of the diseases mentioned here are caused by mosquitoes that thrive on stagnant water.

Toxic food ;

The environmental quality of a region has a direct impact on the food produced in that area. Both vegetarian and non-vegetarian food faces the danger of becoming toxic if the environment it is being grown in is polluted. For eg- chemical wastes that are often dumped in water bodies cause the seafood in that area to become highly toxic.

Chemical pollutants

Cancer nowadays is becoming a household disease. The major reason behind this is that technological development has brought new categories of pollutants. Many of these contain chemicals and compounds that are carcinogenic in nature. This ultimately leads to the development of cancer in most people. 

Climate change and natural calamities

Change in climate disrupts the functioning of nature in many ways that further impact the health of humans. These changes include- the natural temperature of the planet, heavy rainfalls and sandstorms. The numerous impacts of climate may result in a high risk of nervous and respiratory diseases. ;

Hence protecting the environment is extremely important for the life of a human being. The change will come after taking small steps. Numerous small steps can really make a difference.

Environmental Factors That Affect Health

All types of viral hepatitis diseases are contagious and they can be transmitted from one person to another easily. Although, the modes of transmission may vary.

 

Experts recommend some preventive steps for every type of infection to lower your risk of acquiring or spreading hepatitis infection.

 ;

Here are some preventive measures that may help in preventing the infection:

 

Vaccines

Vaccines for hepatitis a and hepatitis b are the best ways to prevent these viruses. Vaccines are not for all types of hepatitis infections. However, hepatitis a vaccination can help prevent the infection caused by the hepatitis a virus. The hepatitis a vaccine is generally administered in 2 doses. Similarly, there are vaccines available for hepatitis b as well. It is administered within 6 months duration. The same vaccine is helpful to prevent hepatitis d as well. There are no vaccines for hepatitis c and hepatitis e currently.

 ;

Reducing exposure

Hepatitis diseases can be transmitted through bodily fluids, water, and food containing the infection. One can lower the risk of contamination by minimizing contact with these agents. Practicing proper and good hygiene is a way to avoid getting hepatitis through these mediums.

 

You can decrease your risk of coming in touch with fluids containing these viruses by avoiding:

 ;


	
	Sharing used needles and razors
	
	
	Using someone else s toothbrush
	
	
	Touching spilled blood
	
	
	Not using condoms and dental dams during sexual contact
	


 

Handwashing

One must trust in personal hygiene to lower the risk of spreading or acquiring the hepatitis virus. Here are some preventive steps you can follow by washing hands:

 ;


	
	Washing your hands thoroughly after accessing the restroom
	
	
	When you get in touch with an infected person's blood, or stool
	
	
	After daycare routine for caretakers
	
	
	After a diaper change, and before serving food.
	


 

Avoiding contaminated consumption:

Contaminated or infected food and water may become the primary causes of hepatitis infection. One should take these precautions to avoid any contaminated consumption of food or water:

 ;


	
	Avoid eating raw shellfish
	
	
	Beware of fruits that have been washed in contaminated water
	
	
	Avoiding unhygienic street vendors
	
	
	Use bottled water for brushing or oral cleaning in areas where clean water is not available
	
	
	Bringing the water to a 1-minute boil is a must in doubtful areas
	
	
	Heated food to be eaten right away
	


Hepatitis: Some Ways To Prevent Yourself

Hepatitis- related to an inflammatory condition of the liver. It occurs mainly due to infection caused by viruses but there are other possible causes as well. Hepatitis can be temporary or viral. Temporary hepatitis, which is acute in nature, gets resolved on its own. Viral hepatitis can be of five types, a, b, c, d, and e.

Symptoms of hepatitis

Hepatitis, in its initial phase, is called the acute phase. The following symptoms along with mild flu are visible:

Loss of appetite
Fatigue
Joint pains
Pain in the abdomen
Nausea
Weight loss
Jaundice
Though this phase is not really dangerous for some patients, it can result in liver failure leading to death.

How is hepatitis diagnosed?

Physical examination
Laboratory tests
Imaging tests


Treatment for hepatitis

Treatment options for different types of hepatitis are:

Hepatitis a: this doesn t require treatment as it is short-term in nature. In case the symptoms cause a lot of discomforts, then bed rest is recommended. The vaccine is available to prevent this infection.

Hepatitis b: acute hepatitis b doesn t require treatment either. Its chronic form can be treated with antiviral medications. This can be prevented with vaccination.

Hepatitis c: this type of hepatitis, both in its acute and chronic forms, is treated through antiviral medications.

Hepatitis d: according to a study in 2013, a drug known as alpha interferon is used to treat this type of hepatitis. Unfortunately, this only comes to the rescue of 25-30% of people.

Hepatitis e: this acute form of hepatitis gets resolved on its own. Adequate rest, drinking a sufficient amount of water, and taking enough nutrients in their food are some of the ways to get healed from this disease.


 

Hepatitis: Signs, Diagnosis, And Treatment

When abnormal cells grow inside the brain and are in the form of a mass the condition is called a brain tumour. There are various types of brain tumours that exist. Some of the brain tumours which exist are malignant or cancerous while other may be non-cancerous. A brain tumour can begin in any part of the brain and spread to other parts of the body or vice-versa. The growth rate of brain tumours is different for each individual suffering from it. As per studies, every 2 in 1, 00, 000 people are said to be affected by a brain tumour in india. However, it may come as a relief to some as not all brain tumours are cancerous or life-threatening. Some are benign tumours and seldom pose any threat to the affected individual.

 

Types of brain tumor

Brain tumours may be primary or secondary.

Primary brain tumour

In this type of brain tumour, the abnormal mass of cells that originated in the brain does not metastasize to the other organs. Based on their location in the brain, the primary brain tumours may be of the following types.


	
	Gliomas: one of the most common types of primary brain tumours, gliomas can have their origin in the spinal cord or the brain. Some of the common types of gliomas include astrocytomas (originates in the cerebrum of the brain), glioblastomas (these tumours form from the astrocytes which form the supportive tissues of the brain), ependymoma (these develop from the ependymal cells which are present within the cns), oligodendrogliomas (these tumours are found to arise from the oligodendrocytes).
	
	
	Schwannomas: also called acoustic neuromas, these primary brain tumours form on the nerves that play an important role in regulating the balance and hearing from the inner ear to the brain.
	
	
	Meningiomas: these types of tumours are usually benign and have their origin in the meninges (membranes surrounding the spinal cord and the brain).
	
	
	Primitive neuroectodermal tumours (pnets): primitive neuroectodermal tumours (pnets) are rare malignant tumours that originate from the fetal (embryonic) cells in the brain.
	
	
	Pituitary adenomas: as the name suggests, these tumours arise from the pituitary gland located at the base of the brain.
	
	
	Medulloblastomas: common among children, these malignant primary tumours develop in the brain (lower back) and gradually spread via the spinal fluid.
	


Other types of primary brain tumours include craniopharyngiomas and germ cell tumours.

Secondary brain tumours ;

Unlike the primary brain tumours, these tumours have their origin in the other body parts and organs (mostly in the lungs, skin, colon, breast, and kidney) and then gradually metastasize to the brain. Secondary brain tumours are found to be more common.

 

What Are The Different Types Of Brain Tumours?

Hepatitis is a condition that affects the liver by causing inflammation which is a common outcome resulting from a viral infection. While different types of hepatitis diseases are caused by different causes, there are some reasons like medications, toxins, alcohol, and drugs that are typically known.

 

Types

The five common types of viral hepatitis are hepatitis a, b, c, d, and e.

 ;


	
	Hepatitis a
	


Hepatitis a is the result of an infection caused by the hepatitis a virus. This type of hepatitis is an acute disease.

 


	
	Hepatitis b
	


The hepatitis b virus causes hepatitis b. This is often a chronic disease that lasts longer.

 ;


	
	Hepatitis c
	


Hepatitis c comes from the hepatitis c virus. It is one of the most common bloodborne infections in the world. It is a long-lasting condition.

 


	
	Hepatitis d
	


This is a not so commonly found form of hepatitis that only occurs in hepatitis b infected people. This virus not only causes liver inflammation but also cannot be contracted without an existing hbv infection.

 ;


	
	Hepatitis e
	


Hepatitis e is waterborne. Hepatitis e virus infection is responsible for it. It is generally acute but can be severely chronic for pregnant women.


 

Causes of viral hepatitis

It is true that different types of viral hepatitis infections are caused by distinct modes of transmission. Here are the causes of a hepatitis infection:

 ;


	
	Hepatitis a- when a person is exposed to the hepatitis a virus through food or water.
	


 


	
	Hepatitis b- when an individual comes in contact with hepatitis b virus through the transmission of bodily fluids like blood, semen, etc.
	


 ;


	
	Hepatitis c- when someone gets infected with the hepatitis c virus through the contamination of bodily fluids.
	


 


	
	Hepatitis d- when a person is exposed to hepatitis d virus-infected blood, it causes this disease.
	


 ;


	
	Hepatitis e- when a person comes in contact with the hepatitis e virus through water or food.
	


 

Causes of non-viral hepatitis

Although hepatitis is commonly caused due to an infection, other factors can also be reasons to cause hepatitis.

 ;

Alcohol

Excessive alcohol can lead to liver damage, causing inflammation. It can also be called alcoholic hepatitis. The alcohol impacts the liver cells directly. Moreover, it can also cause cirrhosis or even permanent liver failure.

 

Autoimmune system response

In rare cases, the immune system of a person attacks the liver itself. It leads to inflammation that can be mild to severe according to the infection. Moreover, it s more common in females than in males.

How Is Hepatitis Caused And Some Common Types?
