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?

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?

Cervical cancer is a ;cancer that affects the cells of the cervix in women. The cancer is believed to be caused by exposure to human papilloma virus (hpv). Also, there are certain factors that are linked to an increased risk of acquiring hpv and developing cervical cancer.

What Are The Major Risk Factors Of Cervical Cancer?

As the name suggests, kidney cancer, also known as renal cancer, starts in the kidneys. It occurs when the healthy kidney cells grow out of control and become malignant to form cancerous tumours. ;Renal cell carcinoma is the most common type of cancer affecting the kidneys  here cancer begins in the lining of the tubes of your kidney.

Risk factors of kidney cancer

The exact cause of kidney cancer is not known. However, studies suggest that certain factors can make you susceptible to renal cancer. These include  


	
	Smoking
	
	
	Overuse of certain medications
	
	
	Excessive body weight
	
	
	Genes/heredity
	
	
	Gender   men rather than women are prone to kidney cancer
	
	
	An underlying health condition, such as ;high blood pressure
	


Early signs of kidney cancer

The symptoms of renal or kidney cancer depend on its types. In most cases, the disease does not exhibit noticeable symptoms in its early stages. This makes the diagnosis of cancer difficult. However, the signs become more apparent and observable as cancer starts to metastasize. You should watch out for these signs of kidney cancer -


	
	Bouts of blood in the urine   a condition commonly known as haematuria
	
	
	Pain on one side of the lower back (near the kidneys)
	
	
	A lump or mass on the lower back or side, where your kidneys are located
	
	
	Loss of appetite
	
	
	Tiredness or ;fatigue
	
	
	Unintentional weight loss
	
	
	Fever ;that does not cure in days
	
	
	Anaemia   low count of the red blood cells
	
	
	In men, a cluster of enlarged veins called varicocele may develop around the testicles (particularly around the right testicle), indicating the presence of a large tumour
	


Often, these symptoms are mistaken for those of other conditions or diseases. Therefore, it is important to consult a specialist.

If you encounter the above symptoms, or if you are concerned about any changes that you have been experiencing lately, talk to your healthcare provider. A doctor will enquire about the symptoms and might ask you questions related to these signs   how long have you been experiencing them, or how severe is the pain etc. This is crucial for early diagnosis and treatment of kidney cancer.

Know How To Detect Kidney Cancer Early

People with sickle cell disease often experience myriad symptoms of the disease that can be controlled by the right nutrition. Reports suggest that nutrition is an increasingly significant factor to prevent symptoms such as slow growth, lower body mass, joint issues, infections, pain crises, and anemia.

There is a greater than the typical requirement for both calories and micronutrients.

The nutritional requirement of a sickle cell patient emphasizes more on vegetables, fruits, whole grains, and more similar food items. These can prevent any deficiencies in the body and also decrease any chances of disease exacerbation.

 


	
	High-calorie nutrient-dense diet
	


The usual energy intake in a sickle cell patient is normally lower than the average values. It is a case even when the condition is asymptomatic where the requirement drops to half the level. As a result, people with sickle cell diseases (especially kids) are at higher risk for impaired growth and considerably lesser fat and fat-free mass, with obesity also posing a risk. It is suggested to have adequate energy supplements in the diet to reach the minimum sufficient requirement of the body that can be done only by proper nutritional assessment.


	
	Adequate fluids
	


Avoiding dehydration is another significant factor to avoid any severe symptoms of sickle cell disease. Sickling of the erythrocytes aggravates in patients who perform hardcore physical work in the heat without drinking enough fluids. This leads to dehydration and can even result in constipation.


	
	Micronutrients
	


Micronutrient deficiencies can be found in sickle cell patients up to a great extent. Several vitamins and minerals like vitamin a, b6, c, e, carotenoids, zinc, and magnesium are often found in fewer numbers in scd patients. A significant drop in blood-antioxidant status may result in acute chest syndrome. The supplementation of these vitamins and minerals can reduce the number of sickled cells in the body. Plant phenols and flavonoids may also help in lowering oxidative stress.


	
	Calcium-rich food
	


Getting plenty of calcium-rich food like dairy products, leafy vegetables, cereals, and fruit juices aids the child's growth and development. This may lead to a stronger physical structure and a greater resistance to the disease.


	
	Omega-3 fatty acid
	


There are reduced proportions of omega-3 polyunsaturated fatty acids in sickle cell patients. These acids aid the fluidity of red blood cell membranes. As a result, they prevent sickle cell crises. Supplemental docosahexaenoic (dha) and eicosapentaenoic (epa) have shown numerous therapeutic benefits in scd patients.
