An allergy is a hypersensitive reaction of the immune system to a foreign substance. The immune system is responsible for producing substances referred to as antibodies. When an individual suffers from allergies, their immune system generates antibodies that help in identifying the harmful allergens affecting the body. The symptoms of allergies are dependent on the substance one has been affected with. The reactions can be mild, moderate or severe in nature. Hay fever Hay fever, which is also called allergic rhinitis, can result in sneezing, runny nose, itching in the eyes or the nose, and watery or swollen eyes.

Atopic dermatitis This is a skin condition, which also goes by the name of eczema.

Alzheimer’s results in the unfortunate wasting away of brain cells, causing their premature death; it is a progressive ailment. It is the most common kind of dementia, wherein a person’s social skills, behavior, and thinking capabilities decline, disrupting their ability of independent functioning. The earliest signs of this disorder may be forgetfulness with severe memory loss as the disease progresses.

Anemia refers to the medical condition in which the body does not produce enough red blood cells to transfer oxygen to the tissues in the body. When you suffer from anemia, you feel weak and exhausted all the time. This disease can be temporary in nature or have a long-term effect on a person’s health, in which case they will require continual treatment. Causes Inflammation Several kinds of diseases like kidney diseases, cancer, rheumatoid arthritis, Crohn’s disease, and chronic inflammatory diseases obstruct the process of producing red blood cells. Iron deficiency anemia This is the most common kind of anemia. As the name suggests, it is a result of a deficiency of iron in the body. The bone marrow requires iron to produce hemoglobin. When there is a shortage of the nutrient, the body fails to generate a sufficient amount of hemoglobin to produce red blood cells. Vitamin-deficiency anemia Apart from iron, the body requires vitamin B-12 and folate to generate red blood cells. When your diet does not have any of these, there is a sharp drop in the red blood cell count. There are also cases of people who consume vitamin B-12 but not absorbing it properly. That gives rise to vitamin-deficiency anemia.

Arthritis is a medical condition that is marked by inflammation in the joints. It can affect a single joint or several joints in the body. There are different types of arthritis. Each one can be traced to a different cause, with various methods to treat them. Types Primarily, there are two main kinds of arthritis – rheumatoid arthritis and osteoarthritis. These can be broken down into several categories. Osteoarthritis This is the most commonly diagnosed form of arthritis. When a person is suffering from osteoarthritis, the cartilage of the joints gets severely damaged. The cartilage is the tough, coarse protective coating found at the end points where the bones come together to form a joint. Cartilage acts as a cushion to this part of the bones and facilitates the frictionless movement of the joints. When the cartilage gets damaged, the bones grind against each other, causing severe pain and restrictive movements. This damage can take place over a few years or in a short time. Rheumatoid arthritis In this type of arthritis, the immune system adversely affects the outer covering or the lining around the joint capsule. The joint capsule is a hard membrane that surrounds parts of the joints.

Blood disorders can be of various types. The most common ones include anemia, bleeding and clotting disorders like hemophilia, and cancers like lymphoma and leukemia. In this article, let’s look at the symptoms, causes, and risk factors associated with some of the common blood disorders. Read on to know more about three common blood disorders. Leukemia Among the most common symptoms of leukemia are extreme fatigue and feeling ill. Additionally, people with leukemia have a tendency to bleed easily; the urine or stool may be accompanied by blood, or patients might bleed from their nose or gums. One may also experience swollen lymph nodes, weight loss, and a loss of appetite. Causes: Leukemia typically develops when the DNA inside the blood cells starts getting damaged, which can cause the blood cells to grow and divide uncontrollably. In this situation, the healthy blood cells die and are replaced by new abnormal cells, which develop inside the bone marrow. However, abnormal blood cells do not die naturally and keep building up. This leads to the cancerous cells overcrowding and outnumbering the healthy cells, resulting in leukemia. Risk factors: The most common risk factor associated with leukemia is the presence of certain viruses (human T-lymphotropic virus) in the body.

When the cells in the lungs begin to abnormally multiply and grow, it results in cancer. Lung cancer is one of the leading causes of death in the world. And the risk of suffering from this life-threatening disease is even higher when one is a smoker. Herein, we discuss the various factors that come into play when it comes to lung cancer. Symptoms of lung cancer Usually, lung cancer does not present any symptoms or signs in the early stages.

If someone is unable to quit smoking, they should visit a medical practitioner for quitting techniques to help avoid this disease. Types of lung cancer There are two kinds of lung cancer: Non-small cell lung cancer This is a catchall term that includes many varieties of this disease, like large cell carcinoma, squamous cell carcinoma, and adenocarcinoma. Small cell lung cancer This happens mainly to people who are heavy smokers, and it’s rarer than non-small cell lung cancer. Risk factors of lung cancer Various factors put you at risk of getting this disease.
