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

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?

The moment you are diagnosed with a tumour, the first thing your doctor will do is find out whether the tumour is benign or malignant   this will determine the course of your treatment. In simple words, benign means non-cancerous while malignant means cancerous.

Benign cancer

When tumour cells grow at a normal pace, it is known as benign or non-cancerous growth. In the case of benign cancer, the cells grow slowly and do not spread to other parts of the body or invade the adjacent tissues. Most often, these do not exhibit serious symptoms or pose a threat to your health. So, they are not a cause of concern. However, sometimes a benign tumour can press against nerves, tissues or the blood vessels, causing pain and discomfort.

Some common types of benign cancer are  


	
	Adenomas
	
	
	Fibromas or fibroids
	
	
	Hemangiomas
	
	
	Lipomas
	


Benign tumours, although tend to be harmless, may need to be operated. This is true for tumours that have grown to become large and weigh heavy. When these develop in the brain and cluster around to press against block channels or vital organs, the condition can be potentially dangerous. Moreover, certain types of non-cancerous tumours like intestinal polyps are precancerous   meaning they have the potential to turn cancerous. ;Surgery to remove this type of tumour can help prevent it from becoming malignant.

Malignant cancer

Malignant cancer refers to cancerous tumours that can potentially be fatal. Unlike benign cancer, malignant cancer progresses quickly and metastasizes to invade other organs, tissues or parts of the body.

Here are a few examples of tumours that are cancerous in nature  


	
	Carcinoma
	
	
	Sarcoma
	
	
	Germ cell tumour
	
	
	Blastoma
	


A tumour that has turned malignant, or has spread through the lymphatic system or bloodstream, may require aggressive treatment. Based on the stage of cancer, your ;oncologist will devise a treatment plan that might include immunotherapy, ;radiation therapy, chemotherapy ;or surgery.

Being diagnosed with a tumour can be hard to deal with. To find out if the tumour is benign or malignant, consult a specialist and discuss your concerns.

Benign Cancer Vs Malignant Cancer: Know The Difference!

Your body needs some cholesterol to produce hormones and vitamins that help in digestion. Two types of lipoproteins   ldl cholesterol and hdl cholesterol   are responsible for carrying cholesterol to and from the cells in your body.

Hdl or high-density cholesterol is good cholesterol. It carries bad cholesterol away from the arteries and other body parts back to the liver to be processed by the liver.

Ldl or low-density cholesterol, also known as the bad cholesterol, contributes to fatty build-ups within the arteries. This results in narrowing of the arteries and increases your risk of cardiovascular diseases like pad, heart attack, or even stroke.

Although there are medications to bring down ldl cholesterol levels, your doctor may recommend using therapeutic lifestyle changes to see how well your cholesterol levels can be managed without medications.

How to reduce  bad  cholesterol naturally

You can lower ldl cholesterol levels naturally with the following measures  

Diet and weight loss

Being obese or overweight not only increases the odds of developing high ldl levels but also contributes to cardiac diseases and chronic conditions. Studies suggest that losing even a little weight may help reduce ldl levels.

Your diet plays an important role in losing excess fat and maintaining ideal body weight. Eating the right kind of food   such as those that contain a good amount of monosaturated fats, phytosterols and soluble fibre   can help lower harmful ldl cholesterol and increase the levels of hdl cholesterol in the blood. Focus on eating whole grains, fruits and leafy vegetables, legumes, nuts and seeds, and fatty fish.

Exercise more often

Exercising regularly, in moderate amounts, can bring down your cholesterol levels and promote weight loss. Any form of cardiovascular activity, such as cycling, running, swimming and jogging benefits your heart health. You may also turn to other forms of exercise   weight training or yoga   as they also work to decrease the levels of bad cholesterol.

Quit smoking

Smoking causes a number of chemical changes in your body. Cigarette smoke increases bad cholesterol (ldl) and triglycerides levels. This leads to the accumulation of waxy plaque, which clogs the arteries. At the same time, smoking reduces the level of good cholesterol   the one that prevents the formation of plaque in your blood. Quit smoking and turn to a healthier lifestyle to see a difference in the levels of your ldl cholesterol.

Limit alcohol consumption

According to studies, heavy alcohol consumption or drinking more than what is considered moderate significantly increases bad cholesterol, which again raises triglyceride levels and ldl cholesterol.

Lifestyle changes are the natural and first line of treatment for people with high cholesterol levels. However, if your doctor suspects these levels could put you at risk of other medical conditions, he/she might recommend medications to manage bad cholesterol.

What are the different types of sickle cell disease?

Sickle cell disease or sickle cell disorder is a term often used to talk about a group of diseases affecting hemoglobin. It is the oxygen-carrying element of blood that makes up 2 alpha globins and 2 beta globins. Sickle cell disease happens due to beta-globin mutation and depending on the abnormality in mutation.

Types-
Sickle cell diseases can be of many types depending on the gene mutation in the blood. Some of the common types are-

Sickle hemoglobin s disease (ss)
Hemoglobin ss disease or sickle cell anemia is the most popular type of scd. It takes place when hemoglobin s gene mutation is inherited from both mother and father. In simple words, it happens when the child inherits one substitution beta-globin gene from each parent. In this type, the body only produces hemoglobin s. It is mostly found in people of african and indian origin.

Sickle hemoglobin- c disease (sc):
Patients with sickle hemoglobin sc disease have a moderately dissimilar swapping in their genes of beta-globin. Here, both hemoglobin c and hemoglobin s are inherited from each parent. It may cause similar symptoms like anemia but remains relatively l. People of west african and mediterranean origin are more prone to this.

Hbs beta-thalassemia
People with this type of scd inherit one sickle cell gene s and one gene for beta-thalassemia from each parent. Zero and plus are the two common types of beta-thalassemia. While beta 0 thalassemia usually takes a severe form, beta + thalassemia is a milder form of the disease.

Sickle beta-zero thalassemia
Beta-zero thalassemia takes form when the child inherits the beta s gene from one parent and beta 0 thalassemia gene mutation from the other. With similar symptoms to anemia, it is a slightly severe form of beta-thalassemia.

Sickle beta-plus thalassemia
Substitutions in both beta-globin genes take place in patients with sickle beta thalassemia (sb) disease. This may even lead to the requirement of blood transfusion if no normal beta globin is produced. Mediterranean and caribbean people are more likely to have this disorder.

Hemoglobin sd, hemoglobin se, and hemoglobin so
These are the few rare and not less common types of sickle cell diseases. They are also less severe. People with these forms of scd inherit one sickle cell gene s and one gene from uncommon hemoglobin (d, e, or o) from each parent.

Sickle cell trait
Hbas
People with sct have one sickle cell gene s and one normal gene a from both mother and father. Ones with this disorder show few to no signs of the disease and usually spend a normal life. However, the risk to their future generations still exists.
 

What Are The Different Types Of Sickle Cell Disease?

Abstract

Background: it is essential to have an understanding of life expectancy and risk factors among patients with sickle cell disease (sickle cell anemia, hemoglobin diseases, and thalassemias). These are required to counsel the patients, target treatment, and plan the right clinical trials.

 

Methods: a research followed 3764 people ranging from birth to 66 years of age and suffering from scd. The procedure was done to understand the life expectancy and calculate the average age at death. Moreover, the study understood the reasons for the death in all 209 adults. It used the proportional-hazards regression analysis to know the risks for an untimely death in adults with sickle cell anemia.

 ;

Results: when the results for young kids and adults with sickle cell anemia were observed, it was found that the average age at death was 48 for women and 42 for men. Moreover, suffering from hemoglobin c disease had an average mortality age of 60 for men and 68 years for women.

 

In people with sickle cell disease, 18% of deaths took place in patients with mainly renal organ failures. 33% of the tested patients were medically free of organ failures but episodes of pain crisis took their life. Out of these patients, 78% experienced chronic pain, chest syndrome, or both, while 22% suffered a stroke that took their lives.

 ;

Clinical modeling showed that people with sickle cell anemia faced acute chest syndrome, seizures, kidney failure, a white-cell count of over 15, 000 per cubic mm, and a low hemoglobin level were related to a risk of early death.

 

Conclusions: results suggested that 50% of patients with sickle cell anemia lived beyond the age of 50. A huge share of those who lost their lives suffered no noticeable chronic organ failure. However, most of them died due to acute episodes of pain or stroke. Early death was seen highest among patients who had symptomatic disease. High levels of fetal hemoglobin suggested improved chances of survival and are assumably a credible source to foresee the risks and other factors related to adult life expectancy.
