Know Eligibility Rules For Donating Blood

Potassium is an essential mineral that helps in healthy functioning of your body   it helps in muscle contractions, fluid balance, and nerve signals. Your body receives the required amount of potassium from specific food sources and processes the same. The excess potassium is eliminated from the bloodstream by your kidneys.

Under normal circumstances, your blood levels should be between 3.5meq/l and 5.5meq/l for potassium to carry on these functions. Healthy kidneys play a vital role in keeping the potassium levels in check.

In case your kidneys are unable to remove excess potassium, it may get stored in your blood, leading to a condition known as hyperkalemia.

The link between your kidneys and potassium

The mineral potassium and your kidneys share an intricate relationship. If the levels of potassium in your blood are too high, it can pose a threat to your cardiac condition   leading to a ;heart attack or ;irregular heartbeat.

Hyperkalemia occurs when the kidneys fail to function properly. Your kidneys work to balance the amount of potassium consumed with that, which is eliminated through urine. Your body takes in potassium through the foods and drinks you consume. In the initial stages of your kidney disorder, they may be able to make up for high levels of potassium. However, as your condition worsens, they may be unable to eliminate enough of the mineral from the body.

How to find out if you have high potassium levels

The only way to figure out if your potassium levels are healthy or too elevated is to go for a blood test. The test measures the level of potassium in the bloodstream.

As long as your kidneys are healthy, your potassium levels will be under control. Therefore, if you have hyperkalemia, or if there are chances of you getting it, you may have to cut back on foods that are high in potassium content. Besides, you will have to rely on diuretics and potassium binders.

How Are Kidney And Potassium Connected?

Blood is one of the most crucial elements of human existence. It works as a commute for oxygen and various nutrients in reaching the cells. These functions make blood a vital source for the body to operate. That said, india needs 38, 000 blood donations every day, which adds up to 5 crore units required in a year. However, only 2.5 crore units are available against the huge unfulfilled numbers. Hence, it is essential to recognize the importance of blood donation.

 

Why is blood donation important?

While blood donations are essential to help people with surgeries, they are equally vital during cancer treatments, chronic diseases, and gruesome injuries. Moreover, they also benefit the donors in a significant way.

 ;

Types of blood donations

Blood donations are of several types through which a single donor has the potential to help nearly three people.

 

Whole blood donation

It is the most common process of donating blood. One pint of blood collected supports numerous patients in the process. It is, then, divided into different components that aid the donation.

 ;

Plasma donation

The process of plasma collection is carried out through a method called apheresis. It divides plasma from other blood components. Its blood clotting abilities help trauma patients and people undergoing cancer treatment.

 

Platelet donation

The collection of platelets is also done using apheresis. Once identified in the donor s blood, the rbcs and the donor gets other fluids back. Cancer patients are the chief beneficiaries of platelets as they play a prominent role during cancer treatments.

 ;

Double red cell donation

Red blood cells are also collected through the apheresis process. It helps donors to donate twice the dose of a whole blood donation. One can help a patient suffering from blood loss using this method.

 

Advantages of blood donation

Blood donations have several advantages that people should know. They help fight many severe health conditions in the human body. Some of them include-


	
	Loss of blood due to internal or external injuries caused by accidents
	
	
	Sickle cell disease or other abnormalities that affect the blood
	
	
	In the treatment of cancer
	
	
	Cardiovascular or orthopedic surgeries
	
	
	Blood disorders
	
	
	Transplant processes
	
	
	Treatments involving plasma
	


 ;

Covid-19

According to food and drug administration (fda) reports, patients who have recovered from covid-19 can help others by donating blood plasma. They contain antibodies that fight the infection, helping their body fight the virus.

 

Benefits for the donor

Even the donors receive many health and social benefits because of blood donation. Where donated blood saves lives, experts suggest that donors can also benefit from the same. Some of these advantages include:

 ;


	
	Boosting cardiovascular health
	
	
	Maintaining blood pressure
	
	
	Contributing to the community
	
	
	Reducing the iron levels
	
	
	Improving overall health
	



 

Why Blood Donation Is Important?

Cushing syndrome occurs due to prolonged exposure to high levels of cortisol hormone. The condition, often referred to as hypercortisolism, affects women   usually between ages 25 and 40   more than men. Nearly 80% of adults and about 47% of children are diagnosed with cushing syndrome.

The most common cause of cushing syndrome is an overproduction of the stress hormone   cortisol   by the adrenal glands. However, it can also result from overuse of steroid drugs.

If you have cushing syndrome, you are likely to notice symptoms like muscle weakness, weight gain, a buffalo lump, irregular periods, sleep disorders, high blood glucose and high blood pressure.

Recent research has claimed to establish a relation between cushing syndrome and high blood pressure   or what is called hypertension in medical terms.

The link between hypertension and cushing syndrome

Hypertension refers to high blood pressure that causes the force of blood to raise against the artery walls. A number of conditions can lead to hypertension, such as poor diet and lifestyle, an underlying health issue, stress, pregnancy and so on.

As your body encounters stress, the adrenal glands produce and release cortisol in the bloodstream. Studies show that producing excess stress hormone can create a host of pathological problems in the body, including hypertension.

Hypertension is a distinguishing feature of endogenous cushing syndrome. High blood pressure in cushing syndrome has a significant correlation with the duration of hypercortisolism and results from the interaction between various pathophysiological methods regulating peripheral vascular resistance, cardiac output, and plasma volume   all of which are elevated in this state.

How to treat the condition

Cushing syndrome is usually treatable and curable. You will be prescribed to stop using steroid drugs that are likely to increase cortisol levels. If the condition does not improve after treatment, you will have to look for ways to manage the symptoms, especially by monitoring your blood pressure. Team up with your doctor and ask for ways to de-stress yourself.

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.
