Do you know who can donate blood to you or who can you donate blood to? Blood donation may not be complex, but it does need to be compatible with yours and vice-versa. The blood types are determined by the presence or absence of certain antigens - substance that can trigger immune response if they are foreign to the body.
There are four major blood groups which are determined by the presence or absence of two antigens, A and B, on the surface of red blood cells. There is also a protein called the Rh factor, which can either be present (+) or absent (-), which creates A+, A-, B+, B-, O+. O-, AB+, AB- blood types.
Group A blood type has only A antigens on red blood cells and B antibody in the plasma. B has only B antigen on red cells and A antibody in the plasma. AB has both A and antigens on red cells, but neither A nor B antibody is present in the plasma. O has neither A nor B antigens on red cells, but both A and B antibody are present in the plasma.
Your blood type determines who can you donate to. This is because there are very specific ways in which blood types must be matched for safe transfusion. The right blood transfusion could actually save you, while the wrong one could be lethal. Also, Rh-negative blood is given to Rh-negative patients and Rh-positive or Rh-negative blood can only be given to Rh-positive patients.
If you are O blood type, you can donate to O, A, B, and AB, if you are A blood type, you can donate to A and AB, if you are B blood type, you can donate to B and AB, however if you are AB, you can only donate to AB.
If you are O blood type, you can only receive from O. If you are A, you can receive from type A and O. If you are blood type B, you can receive from type B and O. If you are AB, you are lucky, you can receive blood from O, A, B, and AB.
There are more than 600 other known antigens, the presence or absence of which creates "rare blood types". Certain types are unique to specific ethnic or racial groups, this is why an African-American blood donation can be the best hope for the needs of patients with sickle cell disease, as per the Red Cross Organization.
Type O is one in high demand, as it can donate blood to anyone. O negative blood type is the universal blood type, which can donate to everyone, especially during the emergency transfusions and for immune deficient infants.
In the US, 37% Caucasian, 47% African-American, 39% Asians, and 53% Latino-American are O-positive. However, only 8% of Caucasian, 4% of African-American, 1% Asian, and 4% Latino=Americans are O-negative.
A+: 33% Caucasian, 34% African-American, 27% Asian, 29% Latino-American
A-: 7% Caucasian, 2% African-American, .5% Asian, 2% Latino-American
B+: 9% Caucasian, 18% African-American, 25% Asian, 9% Latino-American
B-: 2% Caucasian, 2% African-American, .4% Asian, 1% Latino-American
AB+:3% Caucasian, 4% African-American, 7% Asian, 2% Latino-American

There are many myths linked to heart health that can mislead people and prevent them from seeking timely help. This article helps to debunk the myths and keep the heart healthy. It is time to prioritize heart health. Dr Rahul Gupta, Director of Interventional Cardiology and Structural Heart Program, Gleneagles Hospital, Parel, Mumbai, spoke about the common myths about heart disease and listed the facts as well.
Heart problems are commonly seen in people of all age groups. However, heart health is often surrounded by myths and misconceptions that can lead to confusion and poor lifestyle choices in people. So, heart health depends on multiple factors, including diet, activity, stress, and overall lifestyle, and not just one or two habits. Here, the expert helps to debunk the myths associated with heart health and improve the quality of life.
Myth 1: Only older people are at risk of heart problems
Fact: People commonly believe that heart problems can only happen in old age. However, currently, a large number of youngsters aged 25-35 are also struggling with heart issues such as heart attacks and heart failure because of stress, unhealthy diets, and lack of exercise. So, heart problems are not limited only to older people. Anyone, irrespective of their age, can suffer from them. Hence, there is a need of the hour to go for regular heart check-ups and to initiate timely treatment for heart problems.
Myth 2: If you are fit, your heart is SAFE
Fact: So, being physically active is important, but it does not reduce the chances of heart problems. Be attentive to the family history, genetics, and other factors such as high cholesterol or even stress. So, go for cardiac screening on a yearly basis to know the status of your heart health. Discomfort in the arms, jaw, or back and light-headedness can also mean that your heart is in danger.
Myth 3: Heart disease is only seen in men
Fact: Shockingly, heart disease also causes higher morbidity and mortality rates in women. The symptoms seen in women linked to heart disease are dizziness, palpitations, and even giddiness. Hence, women should also focus on their heart health. Stay alert, stay safe!
Your heart health matters. By understanding the facts and making informed choices, it is possible for everyone to protect their heart and overall well-being.

Parkinson's disease is a condition that affects people with Parkinson's ability to move and do things on their own. People with Parkinson's disease will find that it gets worse over time. At first, medicines can help people with Parkinson's disease.
After a while, these medicines might not work as well as they used to for people with Parkinson's disease. Some people with Parkinson's disease might even feel bad because of the medicines they are taking for Parkinson's disease.
That is when doctors might suggest something called Deep Brain Stimulation, or DBS for short, to people with Parkinson's disease. Deep Brain Stimulation is a kind of help for people with Parkinson's disease.
DBS is a kind of surgery where doctors put wires into the brain. These wires are connected to a device that is put under the skin in the chest. This device sends messages to the brain to help it work better. The brain can get mixed up. Cause people to shake or move slowly. The messages from the device help fix that.
One of the things about DBS is that it can help people move better when medicines are not working well. People might shake less. Feel less stiff. They might even be able to take medicine, which can be good because it can reduce the side effects.
It is very important to remember that DBS is not a cure for Parkinson's disease. It does not make the disease go away. It can help people do things on their own again. Many people who have DBS say they can eat, walk, and dress themselves better. These are things that can be very hard for people with Parkinson's disease.
Doctors have to be very careful about whom they recommend DBS to. It is usually for people who take medicines for Parkinson's disease. The medicines do not always work well. The doctors, surgeons, and therapists all have to work to make sure everything goes well.
Exciting things are happening with DBS. Soon, there might be devices that can adjust on their own to help people more. This means that people with Parkinson's disease might have more hope for feeling better.
DBS is a step forward from just taking medicines. It helps people take control of their bodies again. It helps them feel more independent and dignified. That can make a difference in their daily lives. Parkinson's disease is a hard condition to deal with, but with DBS, people might feel like they can do things again. They might feel like they have their life back. DBS is a promising treatment for people with Parkinson's disease.
Chronic stress raises cortisol levels in the body. (Photo credit: iStock)
Work, school, competition—stress appears to be inevitable these days. Across age groups, many are dealing with it in some form or the other, but unfortunately stress never stops at just headaches or fatigue. It has direct effects on an individual's health through causing disease (such as cardiovascular problems); it also has indirect effects on health by negatively influencing other health behaviors such as physical activity and sleep. It is also vital to note that stress is one of the leading health risks for people in the work environment. Healthcare professionals are advised to consider both major stressors and those that occur regularly. Further discussion about stress reduction strategies is provided.
Dr Anshuman Kaushal, Director of Robotic GI, Minimal Access & Bariatric Surgery at CK Birla Hospital, Gurugram, in an interview with Health and Me, spoke about the long-term effects of chronic stress and why it can be termed a lifestyle disorder.
Exposure to certain stressors activates the HPA axis, and as a result, adrenaline and cortisol are released. While these hormones play a crucial role in survival during emergencies, they can result in serious health problems when continuously present in the body. Some of the most common consequences of stress are low immunity, insulin resistance, or inflammation. It can over time result in hypertension or heart disease.
With growing rates of urbanisation, competitive workplaces, financial issues, and the development of technology leading to a permanently accessible Internet, the boundaries between working time and time for rest have been blurred entirely. Moreover, an insufficient amount of sleep, poor sleeping habits, and a sedentary lifestyle cause stress as well. The young generation in India has become victims of stress-related disorders the most.
One of the major challenges when identifying chronic stress cases lies in the subtlety of the condition. The list of symptoms includes constant fatigue, irritability, concentration issues, headaches, tight muscles, and insomnia. Other symptoms of the condition include gastrointestinal disorders such as acid reflux, bloating, and loss of appetite that are hardly ever associated with stress.
Chronic stress may appear harmless, but the truth is quite contrary. When an individual is stressed for too long without controlling it, it may result in anxiety disorders like depression. Physiological side effects of stress are:
While most lifestyle disorders are caused by environmental factors and behavioural alterations, it can be termed a lifestyle disease. These disorders are progressive and require constant intervention in the form of medication or meditation.
Doctors say that it takes a comprehensive strategy to reduce cortisol levels in the body and uplift mood. For instance, workouts like weight training or yoga are known to increase levels of happy hormones, thereby reducing stress. Breathing exercises and meditation, too, have a positive impact on mental health. Experts recommend combining them with nutrition, proper sleep, and socialising.
Early diagnosis matters
Chronic stress is not just a symptom of modern life but also a key health problem. Recognising it as a health issue and addressing it helps combat the long-term consequences well in time. And with continued changes in lifestyle habits and patterns, a lifestyle disease like chronic stress can also be brought under control for the better.
