  Thyroid gland is a very important endocrine gland. It is butterfly shaped and located in our neck. It regulates metabolism and takes part in growth as well. It is regulated by TSH that is released by pituitary gland and in turn it secretes two most important hormones; Thyroxine (T4) Triiodothyronine (T3) When it functions properly, metabolism is normal. Once its activities are disturbed, they change the normal pattern. If thyroid gland becomes underactive it causes hypothyroidism and if it’s hyperactive then it results in hyperthyroidism which is not good in many respects. We’ll focus here on the causes, symptoms, diagnosis and treatment of hyperthyroidism. Causes Inflammation of thyroid gland (thyroiditis) Tumour of thyroid or other glands like that of pituitary gland, testes or avaries Taking more iodine through diet Certain medications that contain T4 which is then converted to triiodothyronine (T3). T3 is very active and makes hyperthyroidism worse. Certain hereditary diseases li

Nowadays, many people including middle-aged ones are complaining about heart problems. They are suffering from different cardiovascular diseases. When they go to the physician, he asks them to bring their lipid profile along with few other blood tests. Here we’ll talk about the most important molecule that belongs to lipid class, it’s cholesterol. What is cholesterol? It is basically an organic molecule that is a type of lipid and belongs to steroid family. It is a waxy substance. Site of synthesis   Liver is the main site where most of the cholesterol is synthesized that caters its requirements for different bodily functions. Dietary sources  We can also obtain cholesterol from different food sources that are usually animal based, like eggs, meat and different dairy products like cheese and yogurt.  Types of cholesterol  There are two main types of cholesterol. Low density lipoprotein (LDL) High density lipoprotein (HDL) LDL is considered as bad type of cholesterol because it gets s

  Endocrine system is a system that consists of all the endocrine glands and their secretions which are called hormones. The study of this endocrine system and associated diseases is known as endocrinology. Let’s see what are endocrine glands. Endocrine glands are the ductless glands that release their secretions (hormones) directly into the blood. Each hormone has got a specific job. The actions they produce in our body account for major physiological processes to happen for e.g. a hormone called thyroxin, plays vital role in metabolism.  Endocrine glands and their secretions   There are different types of endocrine glands which are involved in many different activities through their secretions.  Hypothalamus is one of the main endocrine organs that is located below the thalamus and just above the pituitary gland and releases hormones which control the functioning of pituitary gland. Pituitary gland is the master gland that controls and regulates other endocrine glands. It is loca

A normal person’s heart rate is in between 60 to 100 beats per minute and on average, the heart rate is 72 beats per minute. What happens when your heart beats faster than normal?  Sometimes, it is temporary and goes away as soon as you come out of that situation for example if you have some kind of fear or a particular situation that causes such problem. But sometimes it happens often when you are doing normal work and you experience abnormality in heart rate. This is diagnosed as arrhythmia which is a kind of abnormality or irregularity in the heart rate. Arrhythmia can be in both forms i.e. it may be characterized by increased heart rate or decreased heart rate. When the heart rate is faster i.e. more than 100 heartbeats per minute, it is called tachycardia and when it is lower i.e. less than 60 beats per minute then it is called bradycardia . Both of these conditions ring a health alarm. It’s a medical emergency. Let’s see what are the causes of such arrhythmias Myocardial infarct

  It is a system that is related with respiration and consists of all the respiratory organs. What is respiration? Respiration is the process of liberating energy by the process of food oxidation the system gets oxygen for breathing from the environment and also removes carbon dioxide gas in turn. Respiratory organs The human respiratory system typically includes the following organs that help in the exchange of gases. nose pharynx larynx trachea bronchi bronchioles alveoli lungs Nose consists of two nostrils. Each has got the tiny hairs (cilia), mucus membrane, blood capillaries. It not only serves as a sense organ for smelling things but also acts as a passage of air. The tiny hairs filter the air while mucus sticks any solid particle like dust or any other substance however blood capillaries help in warming up the air that is entering inside the other respiratory organs. Pharynx is a part of the throat and serves as a passage for both air and food. There

  The temperature was high and air was dry. Water was dripping through eyes though I was not weeping, still tears were oozing out. What’s the reason? I checked the temperature and surprised to see it was 40°C. Well, everybody is bearing the worst effect of global warming around the world, it’s heat stroke! This is also known as Sun stroke.

Various campaigns were run by private and public sectors to create  awareness among the masses about the severity of this heat stroke and associated health risks . Media played major role in this campaign and guided What to do in this situation. So what’s heat stroke? It’s a condition that is caused due to the elevating temperature in the surrounding.
