Now let’s see why obesity is harmful, and how much harm does it can cause?
Being obese can make a person less confident and less motivated in social life. Obesity can put restrictions on the free movements of a person which reflects in his/her social behaviour.
Is it the only problem that we should be worried?
Unfortunately, the answer is No! Social and cosmetic issues associated with obesity are just the tip of an iceberg. The real problem is far more dangerous, and most of the time, it is not apparent externally, which is the cause of real worry.
Obesity is associated with multiple health problems like Diabetes, High blood pressure, High cholesterol levels, Heart attacks. It is collectively known as Metabolic Syndrome. It may result in significant morbidity and can be life-threatening; that too, at a very early age, which makes the obesity a grave issue. Today, obesity is spreading like an epidemic all over the world. We need to be aware of its hazards and be prepared to fight against it.
In this article, we will be discussing the health issues associated with obesity. It is important to note that majority of health problems due to obesity are associated with high levels of visceral fat. It may not be noticeable externally, but present hidden deep inside our body.
The health hazards associated with obesity are:
INSULIN RESISTANCE AND DIABETES:
ABNORMAL BLOOD CHOLESTEROL LEVELS:
Excess amount of body fat (visceral fat) is associated with a rise in blood cholesterol levels. The level of LDL (Bad) Cholesterol increases and that of HDL (Good) cholesterol decreases. This imbalance between good and harmful cholesterol levels can lead to a severe health problem.
HIGH BLOOD PRESSURE:
EFFECT ON BLOOD VESSELS:
Obesity is responsible for the increase in the levels of LDL Cholesterol (Bad Cholesterol)and triglycerides in the blood. It gets deposited along the walls of blood vessels like arteries and veins in the form of plaques. The walls of these blood vessels become hard, less flexible, and the lumen becomes narrow. It reduces the blood flow to the vital organs, which can have grave consequences.
INCREASE CLOT FORMATION (INCREASE IN BLOOD COAGULABILITY) IN BLOOD:
INCREASED CHANCES OF CHEST PAIN AND HEART ATTACKS:
PARALYSIS (Stroke):
A blood clot formed in the blood vessel (due to increased clot-forming ability of blood in an obese person) within the body sometimes gets dislodged, travels through the circulation and gets stuck inside a small blood vessel supplying the brain and blocks it. Similarly, if a plaque is formed within the lumen of a blood vessel supplying the brain, it can reduce the flow of blood considerably. It can deprive the brain of oxygen and nutrition, which can cause damage to the brain tissue and manifests as paralysis/stroke.
HEART FAILURE:
Heart failure means the failure of the heart as a pump. There are multiple mechanisms which can contribute to it.
Weak heart muscle decreases the capacity of the heart to function at an optimum level and put an obese individual at the risk of heart failure and early death.
RESPIRATORY PROBLEMS:
Obesity is associated with multiple Respiratory problems, such as;
POLYCYSTIC OVARIAN SYNDROME AND INFERTILITY:
Obesity (Visceral Obesity) is responsible for the development of insulin resistance. Insulin which is secreted by pancreas fails to metabolize blood sugar effectively. The excess levels of insulin in the blood causes the secretion of the hormone called Androgen. Fat cells convert Androgen into estrogen. In women, this excess estrogen along with Androgen disrupts the normal function of ovaries, and increase the chances of developing polycystic ovarian syndrome (PCOS). Having Polycystic Ovarian syndrome is a risk factor for infertility.
OBESITY INDUCED COMPLICATION DURING PREGNANCY
Obese women are likely to experience certain complications during pregnancy, such as,
GASTROINTESTINAL PROBLEMS ASSOCIATED WITH OBESITY:
Both these conditions are responsible for causing an injury to the covering (mucosa) of the inner wall of the stomach and food pipe (oesophagus). It manifests as heartburn/acidity.
Obesity develops insulin resistance. The excess insulin present in the body triggers the release of certain harmful chemicals like free fatty acids from the fat tissues. These free fatty acids get accumulated within the liver. Under normal conditions, the liver can effectively metabolize these fatty acids. When the rate of accumulation exceeds the rate of metabolism, these free fatty acids get deposited within the liver as adipose (fat) tissue. Presence of excess amount of fatty tissues in the liver results in programmed death of liver cells, ultimately leading to liver failure.
Presence of abdominal obesity with an excess amount of visceral fats increases the cholesterol formation within the bile in the gall bladder. Deposition of excess visceral fat reduces the motility of gallbladder. It causes stasis of bile stasis, resulting in deposition of cholesterol (present in bile) in the form of stones within the gallbladder.
HERNIA means a protrusion of an intraabdominal content (Omentum, intestines, bladder, etc.) or it’s part through a defect in abdominal musculature. The excess of visceral fat in an obese person weakens the abdominal wall muscles. Besides, obesity increases intraabdominal pressure. Both these conditions contribute together in the protrusion of intraabdominal content and development of hernias.
MALE INFERTILITY:
Abdominal obesity is associated with increased deposition of visceral fat. The excess fat deposition increases secretion of estrogen (female sex hormone), and at the same time decreases the levels of male sex hormone (testosterone). Both these things result in a reduction in sperm count, increasing the risk of male infertility.
MUSCULOSKELETAL PROBLEMS ASSOCIATED WITH OBESITY
There are multiple reasons responsible for the development of osteoarthritis (Pain and friction in joint) in an obese person.
Both these mechanisms eventually destroy the joint to create pain and friction
Osteoporosis is a condition where bones become fragile, brittle and can break easily. Obesity is one of the major factor responsible for it. Let’s see how
The fatty tissue that is present in an obese individual is chemically active. It secretes certain pro-inflammatory chemicals. These chemicals create inflammation and damage the joint tissues at multiple locations in the body. It puts an individual at the risk of Rheumatoid arthritis and joint damage.
EFFECT OF OBESITY ON SKIN:
Leptin is a hormone which, along with other factors, plays an essential role in the wound healing process. In an obese individual, the excess amount of fatty tissue increases the secretion of leptin. Due to leptin resistance, this excess leptin remains inactive, which can delay the process of wound healing.
Excess of fat gets accumulated beneath the skin in an obese individual. It increases the number of skin folds. The sweat remains trapped within these folds. The toxins, along with the sweat trapped within these skin folds, favour the growth of infective microorganisms. It increases the risk of skin infections.
RISK OF CANCERS:
Fatty tissue in our body is chemically active. More the obese a person is more the amount of adipose (fat) tissue in his body. This chemically active fatty tissue releases specific proteins and hormones, which act as chemical messengers and affect the normal functioning of the body. Many times it results in the development of different types of cancers. E.g.
