Diabetes

What exactly is diabetes?

Diabetes is a disease that occurs when the pancreas fail to provide enough insulin for the body, or when the body is not able to use the insulin that is produced.

Insulin is a hormone that helps the body to pass glucose from the food that we eat into the cells. When the body is unable to get enough sugar or glucose (which is necessary to produce energy), it leads to high blood sugar levels.

Glucose is one of the body’s main energy sources. So, when there is lack of insulin, the sugar just builds up in the blood, which apparently causes many health complications.

How it affects your body on long term basis

Types Of Diabetes

There are four main types of diabetes:
1) Type 1 
2) Type 2 
3) Gestational 
4) Prediabetes

Symptoms

Type 1 diabetes:

This is a disease which is believed to be an autoimmune condition. It can develop at any age, but occurs mostly in children or young people. It was also used to be called juvenile diabetes.

The immune system mistakenly attacks and destroys insulin-making cells in the pancreas (beta cells) and the damage is said to be permanent, which means there has to be daily intake of insulin through insulin injections to control blood sugar levels.

Signs and Symptoms of Type 1 Diabetes

They are usually subtle signs but they can turn to severe. Some of the common symptoms are:

  • Often thirsty or hungry
  • Frequent urination
  • Weight loss (even though you’re eating properly)
  • Vomiting
  • Fatigue or laziness
  • Heavy breathing (sometimes)
  • Dry mouth

Type 1 Complications and Causes

Since, damage to beta cells is so overwhelming that glucose won’t go into the cells due to absence of insulin. This causes high blood sugar which lead to:

1) Weight loss: When you urinate, it also takes calories with it which causes you to lose weight.

2) Dehydration: This happens because of extra sugar in the blood. You urinate more and it is your body’s natural process to get rid of it. Water content in the body lessens due to frequent urination and hence causes dehydration.

3) Damage to health: Chronic high glucose levels in your blood can harm the nerves, eyes, heart and kidneys. Also, it is more likely to harden your arteries, which can cause heart attacks and strokes.

The cause of type 1 is still unclear but they believe that there could be genetic and environmental factors involved.

Most of the doctors assume that it is the genes that plays an important role in causing it. Although, they also believe that there might be something around, like a toxin or contagion, that triggers your immune system to attack the pancreas.

Type 1 affects males and females equally. It can happen along with other autoimmune diseases as well.

Type 2 diabetes

This condition is also considered a life long disease that involves insulin resistance, meaning your body stops using insulin the way it should normally.

This is the most common form of diabetes. Usually middle-aged or older people tend to get this type. It used to be called as adult-onset diabetes. Although, it can also affect kids and teens mostly due to obesity or being overweight.

When type 2 gets out of control, it can lead to high blood sugar levels which could be chronic and potentially lead to serious health problems.

Signs and Symptoms of Type 2 Diabetes
  • Blurry vision
  • Mood changes or being cranky
  •  Feeling worn out
  •  Feeling hungry most times
  •  Weight loss
  • Tingling or numbness sensation in the hands or feet
  • Vulnerable to infections
Causes:

In this case, pancreas do produce insulin but the cells don’t use it the way they should. Initially, pancreas make more insulin to help glucose get into your cells, but your body and cells can’t keep up, so this extra glucose builds up in your blood.

Generally, there are several factors involved that cause type 2 diabetes. They include:

1) Genetic reasons: It has been found that different bits of DNA can affect your insulin making process.

2) Obesity or over weight: Extra pounds of weight can cause insulin resistance, especially around your belly.

3) Liver producing excess glucose: Normally, your liver produces glucose when your blood sugar is low. After you eat, blood sugar goes up and then liver slows down its process and stores sugar/glucose for later.

However, some people’s livers don’t and they keep sending out glucose which isn’t good for the long run.

4) Improper transmission between cells: At times, cells send incorrect signals or don’t carry messages correctly. When these affect how the cells use insulin or glucose, a reaction happens that can lead to high blood sugar.

5) Related health conditions: People with type 2 often have problems like high blood pressure, high cholesterol, extra fat around the waist and triglycerides.

Gestational diabetes

gestational diabetes
Gestational Diabetes

It is a condition which affects pregnant women. Like other types of diabetes, this also affects how the cells use sugar or glucose in the body.

In most cases, there usually are no symptoms. However, there are two classes of gestational diabetes:

1) Class A1: Women under this category can manage it with diet and exercise.

2) Class A2: They need to take insulin and other medications.

Normally, it goes away after women give birth. But sometimes, it can affect baby’s health and they have higher chances of developing type 2 later in life.

Signs and Symptoms Of Gestational Diabetes
  • More thirsty than usual
  • Increased appetite
  • Frequent peeing

Prediabetes

This condition happens when your blood sugar level is higher than normal but not high enough to get diagnosed as type 2 diabetes. They call this impaired glucose tolerance.

This is a very common form of diabetes in the U.S, about 84 million people have prediabetes and most of them don’t know that they have it.

It can also turn into type 2 within 10 years when one doesn’t intervene during this period. With proper routine, that includes diet and exercise to manage weight, it’s completely possible to bring blood sugar level back to normal.

Symptoms of Prediabetes
  • Blurry vision
  • Fatigue or tiredness
  • Frequent urination
  • Thirstier than usual
Causes and Risk Factors

You’re more likely to suffer from prediabetes if:

1) Your diet mostly consists of red or processed meat, sugary beverages etc.

2) You’re obese or over weight.

3) You engage in less physical activities.

4) You’re Older, especially over 40

5) You have sleep apnea, insomnia or other sleep related issues.
