Human Health & Disease

consider a situation when we feel that we are not able to perform our daily activity smoothly we decide to visit a doctor because we are unsure about certain signals being exhibited by our body this very unusual feeling is called an illness after waiting for long when we finally get to speak all about our symptoms to the doctor he suggests some tests and on the basis of the results he confirms a medical condition this actual condition that causes us to have discomfort is what we call a disease so in this session let's understand in detail the link between bizzy's and human health health is wealth is what we often hear from all the doctors or health practitioners who always promote a healthy diet and lifestyle we hear it so much that most of us never really think much about what it really means health is most often considered to be a state of complete physical well-being but it is even important for us to be mentally and socially healthy for we can be really happy if we are healthy from within but many would also say that to be healthy means one should not have any illness or one should be disease-free that is absolutely correct - our doctor examines so many people during the day who are suffering from some or other disease so it is important for him to understand diseases better and since we are very much responsible for our own well-being let us also try to understand them today and we can start by classifying them appropriately first we can categorize them into two types on the basis of the onset or have the really big the first type comprises of diseases that are present since birth as they are inherited by a child from its parents also called the congenital diseases majority of the cases are related to defective formation of certain organs or

body parts while the baby was in the womb according to a case study nearly 6 lakh babies born each year in India are affected by congenital defects and majority of this are related to heart followed by inherited genetic changes and infections on the contrary there are diseases which are developed after birth such as diabetes as most of these diseases are acquired in some form or the other they are called as acquired diseases now on the basis of how a disease gets transmitted from one person to another acquired disease are further classified into two types first is communicable disease which spreads from an infected person to a healthier person these may spread directly that is via physical contact or through droplets or indirectly that is if it spreads through contaminated water it is called as waterborne if it spreads through a results in air it is called as airborne then through contaminated food is called as foot borne through infected inanimate objects is called for mite born and the one which spread through flies insects it is called as vector work now can you guess the second category of acquired diseases yes these are the non communicable diseases which do not spread from one person to another according to a whi report non communicable diseases kill nearly 38 million people each year there are certain risk factors involved in developing and non communicable disease which includes age gender genetics exposure to pollution behavior such as smoking and healthy diet physical inactivity hypertension and obesity they are also caused by biological infectious agents such as viruses cardiovascular diseases like heart attacks and stroke cancers respiratory diseases such as obstructive pulmonary disease and diabetes are four main types of non communicable diseases you might have also noticed sometimes we fall ill only for few days and how it can even take weeks to recover before we become healthy again so depending on the duration diseases are also termed as acute disease something that is characterized by sudden onset of symptoms also they are severe in nature and last for shorter periods of time example acute leukemia common cold heart attack whereas chronic diseases are long-term medical conditions that are progressive such as chronic respiratory problems diabetes disease therefore depends on many factors which may be due to unhealthy lifestyle or genetic changes but they happen majorly because of infections these infections are due to the invasion of foreign entities in our body these disease-causing agents are called as micro organism they are single-celled invisible to human eye and have existed for billions of years on this planet they are present everywhere they live in the water you drink the food you eat and the air you breathe they are present even in the body so to what extent do these ubiquitous micro organisms affect our health to answer this question do make sure to check out upcoming session where we'll try to find out if micro organisms are our friends or for an important thing to note here is that if we even bring a small helpful change in our habits and adopt a healthy lifestyle most of this acquired disease can be kept at bay successfully.
