Know Eligibility Rules For Donating Blood

Type 1 diabetes occurs when your pancreas is unable to produce enough insulin to keep the blood sugar ;levels under control. The condition, if not managed properly, can lead to related health disorders and complications, both long-term and short-term.

Health problems arising from type 1 diabetes

Type 1 diabetes can have severe effects on your eyes, kidney, nervous system, and heart health. The most common ailments associated with type 1 diabetes may include the following-

1. Diabetic retinopathy

Diabetic retinopathy is a disease of the eyes, which occurs when the blood vessels in the retina (tissue present at the back of your eyes) are damaged. The walls of the retina gradually weaken from increasing blood pressure and blood sugar levels, and this leads to leakage of blood or fluid into the nearby tissues.

Early symptoms of diabetic retinopathy include-


	
	Blurred vision
	
	
	Floaters
	
	
	Difficulty perceiving colors
	


2. ;Diabetic neuropathy

Diabetic neuropathy unfolds when the nerves are damaged due to type 1 diabetes. The condition mostly affects your feet and legs. Reduced blood circulation due to high blood glucose impedes normal wound healing in the extremities, hence, even a minor bruise ;can develop into a permanent injury.

Symptoms of diabetic neuropathy are-


	
	Numbness
	
	
	Reduced sensation
	
	
	Severe, debilitating pain in the extremities
	


3. Diabetic nephropathy

Also known as ;diabetic kidney disease, the condition is a slow deterioration of the kidney and its ability to function properly. In severe cases, where the levels of blood glucose are extremely high due to type 1 diabetes, diabetic nephropathy can ultimately result in kidney failure ;or end-stage renal disease (esrd).

The following are the symptoms of diabetic nephropathy-


	
	Dark urine
	
	
	Swollen ankles, feet, eyes, or hands
	
	
	Shortness of breath
	


4. Cardiovascular diseases

Cardiovascular diseases refer to a range of heart conditions including blood clots and diseased blood vessels. High blood glucose levels resulting from type 1 diabetes can contribute to the deposition of fat in the walls of the blood vessel. Over time, this may restrict the flow of blood and put you at risk of cardiovascular disorders such as coronary artery disease, stroke, or even ;heart attack.

Symptoms of cardiovascular diseases widely vary, ranging from palpitations ;to chest pain. Sometimes, such a condition may not exhibit any symptoms at all.

Type 1 diabetes complications are related to poor management of blood glucose. The best way to monitor the condition and control the symptoms is to get in touch with your doctor. A specialist in this field can prescribe the correct treatment and help prevent the onset the related health disorders.

Complications Associated With Type 1 Diabetes

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?

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

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.

Role Of Nutrition In Sickle Cell Disease

The most common forms of diabetes ;are type 1 and type 2 diabetes. In type 1, your immune system damages the cells inside the pancreas that produce insulin. Therefore, the pancreas are unable to produce an adequate amount of insulin.

In type 2 diabetes, your body does not respond properly to the insulin produced by the pancreas. As a result, your body will have a difficult time removing sugar ;from the blood. The cells may stop insulin production over time that may lead to insulin deficiency. However, there are other forms of diabetes that are lesser-known but can affect you just as bad.

Types of diabetes beyond type 1 and type 2

Gestational diabetes

In gestation diabetes, a condition that affects pregnant women, the blood sugar levels increase to an extent that may hamper the health of the mother and the child.

Symptoms

Usually, there are no symptoms as such. If diabetes worsens, women may observe symptoms such as -


	
	A need to pee more frequently
	
	
	Excessive thirst and hunger
	
	
	Dryness in the mouth
	


Lada (latent autoimmune diabetes in adults)

It is sometimes referred to as type 1.5 diabetes. Here, your immune system kills the insulin-producing cells inside the pancreas. As this condition takes a longer period to develop, you may not need insulin for many months after you have been diagnosed.

Symptoms

You may observe the following symptoms  


	
	Dryness and itchiness
	
	
	Tingling sensation in feet or hands
	
	
	Blurry vision
	
	
	Frequent urination
	


Mody (maturity-onset diabetes of the young)

This condition is observed during adolescence. Here, genetic mutations limit the pancreas from making insulin. So, due to insufficient insulin, your blood sugar level goes up. If any of your parents have mody, you are likely to have the condition.

Symptoms

Symptoms may include  


	
	Yeast and ;skin infections
	
	
	Frequent urination
	
	
	An urge to pee more often
	


Treatment

Primary care for these other forms of diabetes follows the usual course of treatment as with type 1 and type 2.


	
	Diabetic medications
	
	
	Insulin shots or injections
	
	
	Dietary changes
	


The doctor may instruct you to monitor your blood sugar levels frequently to keep it under control. This will be accompanied by a diet ;consisting of adequate calories, but avoid fatty foods, excess sugar and carbohydrates. Mild exercise is also recommended.

The best way to prevent these conditions is to visit your doctor frequently and follow the treatment plan. Do not keep your diabetes untreated.
