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.

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.

Kidney - prolonged periods of stress can indirectly hurt your kidneys. So you need to be stress free to keep your kidneys healthy.

Stress And Kidney Failure: Are They Connected?

Headaches are extremely common   we all are familiar with mild or persistent throbbing ;pain. A number of conditions can result in headaches. Some of these include  


	
	Fatigue
	
	
	Lack of sleep
	
	
	Stress/tension
	
	
	An underlying condition, like migraine ;or sinusitis
	


Recent studies have revealed a lesser-known cause for headaches   ;hypertension, or what is commonly referred to as high blood pressure.

The connection between hypertension and headaches

Hypertension occurs when the force of the blood circulation in the arteries is elevated   this particular condition can lead to steady pain throughout the head, particularly at the back of the head or in forehead.

Hypertension-induced headaches usually affect both sides of the head, particularly the temple regions. However, a person may not even realize that the headaches he/she is experiencing are induced by high blood pressure.

Since hypertension is an asymptotic condition, it is often referred to as  the silent killer . When blood pressure rises above 180/110, the condition is known as  hypertensive emergency .

Different types of hypertension leading to headaches

There are three types of hypertension conditions that are followed by mild to severe headaches:


	
	Malignant hypertension- this refers to a sudden, rapid increase in blood pressure that calls for medical attention. This is more common among young adults and women with pregnancy-induced hypertension.
	
	
	Idiopathic ;intracranial hypertension- it is characterized by elevated blood pressure around the brain. Symptoms include vision problems, nausea, ;shoulder pain, thumping noise in the ears, and severe headaches.
	
	
	Hypertensive encephalopathy- this is an extreme condition of high blood pressure, which leads to swelling in the brain. A person with this condition experiences severe headache that becomes worse.
	


Uncontrolled hypertension can be dangerous   headaches induced by such a condition could also become frequent or worsen over time. However, with proper medications and certain lifestyle changes, high blood pressure can be kept under the normal measure. Once your blood pressure normalizes, the headaches will disappear in no time.

How Are Hypertension And Headaches Related?

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

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.
