Atherosclerosis refers to a medical condition in which the arteries become hardened and narrowed due to the accumulation of cholesterol plaque in the walls of the artery, obstructing the flow of blood.

What are the causes?

Atherosclerosis is a slow but progressive disorder that starts with the damage of endothelium   cells lining the interior surface of lymphatic and blood vessels. This allows bad ldl cholesterol to build up in the artery walls. Over time, a plaque made of calcium, macrophages, and cholesterol grows to a certain size to clog up arteries, disrupting blood flow around the body.

Other factors leading to atherosclerosis to include  

High blood pressure

High levels of triglyceride in the blood

High cholesterol levels

Certain medical conditions   diabetes, obesity, insulin resistance

Smoking/use of tobacco

Inflammatory conditions like lupus and arthritis

Symptoms of atherosclerosis

Atherosclerosis may develop in childhood or during adolescence. Mild conditions may not reveal observable symptoms unless the arteries are clogged, and blood supply to the tissues and organs are restricted.

Signs of moderate to severe atherosclerosis depend on the affected arteries   it could be the arteries leading to your brain, your heart, legs and arms, or the kidney. The symptoms of atherosclerosis include  

Weakness and fatigue

Difficulty breathing/concentrating

Headaches

Facial numbness

Paralysis

Vomiting

Chest pain

Anxiety

Loss of appetite

Swelling in the feet and hands

If any of the above symptoms seem familiar to you, consult a doctor right away for treatment.

Can atherosclerosis be prevented?

The best way to avoid cholesterol plaque from building up in the artery walls is to prevent the onset of atherosclerosis with these preventive measures.

Eat healthy   avoid eating foods that are rich in saturated fats   red meat, butter and cheese. These increase your cholesterol levels drastically. Instead, include foods that contain unsaturated fats, like avocados, olive oil, fatty fish, nuts and seeds because these help to keep ldl or bad cholesterol levels down.

Stay active   exercising and staying active can help regulate your cholesterol levels and prevent certain conditions that might put you at risk for atherosclerosis.

Quit smoking   people who smoke should quit smoking because it is a major risk factor for atherosclerosis   it increases blood pressure, which in turn, affects your cholesterol levels.

Atherosclerosis can lead to complications. With precautionary measures and proper treatment, the condition can be avoided.

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?

Blood donation is a process that is carried out when a person voluntarily offers for blood to be extracted from his body. There are countless myths about blood donation that need to be squashed and awareness is the only way of doing it.

While blood donation brings multiple health benefits to both the donor and recipient, some facts are known to only a few. These facts will not only open doors to endless possibilities, but will make people feel confident about it.

Facts

Here are some lesser-known facts about blood donation- every person should know-

 


	
	Approximately 112.5 million units of blood are collected from blood donation globally.
	
	
	Around 30 million units are transfused annually.
	
	
	Any person in sound health, at least 18 years old, and weighing at least 45 kilograms can donate blood every 56 days.
	
	
	Your one unit of donated blood can save up to 3 lives.
	
	
	A, b, ab, and o are the primary blood groups. While ab is a universal recipient, o negative is a universal donor.
	
	
	The blood donation process normally takes less than 10-12 minutes.
	
	
	Donating blood does not make you physically weak or decrease your strength.
	
	
	Only 1% of india's population donates blood each year, leading to an annual deficit of two million units.
	
	
	All donated blood units are tested for diseases like hepatitis b, hepatitis c, hiv, and syphilis before transfusion.
	
	
	Red cells, plasma, cryoprecipitate, and platelets are the various types of transfusable elements derived from the blood. The procedure takes place using a method called apheresis.
	
	
	Red blood cells carry oxygen to the organs.
	
	
	Red blood cells survive for about four months in the system of circulation.
	
	
	Platelets encourage blood clotting and provide leukemia patients and other cancer patients with better treatment.
	
	
	Plasma is a pale yellow combination of proteins, salts, and water.
	
	
	Plasma is 55 percent of the volume of blood and 90 percent water.
	
	
	White cells are the chief defense of the body against infections.
	
	
	There is no alternative for blood donation as blood cannot be manufactured.
	
	
	You cannot contract aids or other infectious diseases due to blood donation.
	


Lesser Known Facts About Blood Donation

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.

Reduce LDL Cholesterol With These Easy Steps

World hepatitis day is observed on july 28th every year to raise awareness about hepatitis disease among people. It is organized on the occasion of the birthday of Dr. Baruch blumberg who found the hepatitis b virus in the year 1967 and also developed a vaccine for it. Moreover, this day educates everyone about hepatitis infections, the efforts to fight viral hepatitis, and methods people can use for its prevention.

What is viral hepatitis?

Viral hepatitis or hepatitis disease is a condition of inflammation in the liver that leads to severe liver disease and hepatocellular cancer. With deaths happening every 30 secs from a hepatitis-related infection, it is important to treat viral hepatitis at the earliest. Hepatitis is of different types depending on the infection. 

 ;

Types

Viral hepatitis impacts millions worldwide, resulting in both acute and chronic diseases. There are five major classifications of viral hepatitis-

 


	
	Hepatitis a- it is a liver infection that can be prevented by a vaccine. It is a result of the infection as a result of the hepatitis a virus.
	
	
	Hepatitis b- it is an infection that happens due to the hepatitis b virus. It is spread through the blood or other bodily fluids of a person.
	
	
	Hepatitis c- it is a liver infection caused by the hepatitis c virus. It transmits through the blood of a person who is infected.
	
	
	Hepatitis d- delta hepatitis is another name for this virus and the hepatitis d virus is responsible for this. It happens to only those who are already hepatitis b infected. ;
	
	
	Hepatitis e- it is a liver infection resulting from a hepatitis e infection. It is usually found in a person s stool.
	


 

Symptoms

Hepatitis is a condition where you don t show symptoms till it is chronic and starts affecting your liver health. However, people in the initial stages of hepatitis infection might start reflecting symptoms. Some common symptoms of viral hepatitis are:

 ;


	
	Flu-like signs
	
	
	Darker urine color
	
	
	Fatigue
	
	
	Abdominal cramps and pain
	
	
	Appetite loss
	
	
	Weight loss
	
	
	Yellow skin
	
	
	Pale eyes
	


 

People at risk

The risk of catching a hepatitis infection is high in individuals working around these environments-

 ;


	
	Direct contact with hepatitis a infected person
	
	
	Male in sexual relation with another male
	
	
	Drugs abuser
	
	
	Ones with clotting factor disorder
