Everyone knows the importance of oxygen in our lives. The oxygen we breathe is carried to all the tissues in our body by the red blood cells present in the blood. When there is a lack of healthy red blood cells in the body, the condition is known as anemia. This means that an adequate amount of oxygen is not delivered to some tissues and this can lead to tiredness and fatigue in the body. Anemia is of different types and each type of anemia is caused by a different issue, treating which could be the required solution to the condition. The main types of anemia and their causes are as follows: Iron deficiency anemia Iron is required for the synthesis of hemoglobin, which is required by the red blood cells. When there is iron deficiency, the bone marrow cannot produce enough hemoglobin for red blood cells rendering them inefficient at their work of carrying oxygen to the tissues. This condition is caused by heavy blood loss caused due to ulcers, cancer, heavy menstrual bleeding, inflammation of the stomach lining, etc. Vitamin deficiency anemia Vitamin B-12 and folate are required for the production of healthy red blood cells. When the body experiences a deficiency of these essential vitamins, red blood cell production will reduce leading to this type of anemia.

Listed here are three common eye infections that affect children. Conjunctivitis Also called pink eye, it is one of the most common eye infections in children. Bacteria, virus, or allergic reactions to certain things cause conjunctivitis. Also, the discharge from an infected person transmitted through touch, cough or sneeze, through shared objects like towels, and contaminated water (while swimming) can cause conjunctivitis. Symptoms Bacterial infection results in inflamed or puffy eyelids, pinkish or reddishness in one or both eyes, irritation in the eyes, yellowish-green discharge from the eyes which is most noticed early in the morning after waking up and that tends to crust up. Viral infection causes constant tearing up, urge to rub the eyes, pinkishness in the eyes, swelling, and sensitivity to bright light. This could affect only one eye sometimes. However, conjunctivitis caused by allergy makes the eyes red, itchy and watery, the nosy runny, and could cause frequent sneezing, but there is no discharge. Bacterial and viral conjunctivitis is contagious, while allergic conjunctivitis is not. Treatments Antibiotics in the form of eye drops, ointments, or oral medicines can combat bacterial infections. For eye infection caused by viruses, there is no medication. A simple warm water compress will help keep the eye clean.

Breast cancer is a prevalent cancer among women, as well as some men patients. Breast cancer originates in the tissues and lobules of the breast. Certain risk factors for breast cancer include age, gender, and family genetics that cannot be changed, but risk factors like leading a sedentary lifestyle, being overweight, eating unhealthily, and smoking can be changed. There are also early warning signs of breast cancer that require immediate medical attention, such as: 1. Changes in and around the breast Skin changes in the breast could be a crucial sign that cancer may be present. These changes include swelling, redness, and other signs that are visibly noticeable. These differences can be in either one of the breasts, or in both breasts. Other visible changes could be in the size of the breast or nipple. It can be that the shape of the breast has changed, or that it has gotten larger. The nipples can be different in appearance, and they may have a discharge other than breast milk. The breast may have a lump or a mass, nipple refraction, or turned inward, and the breast could appear thickened, scaly, or red. 2. Dimpling of the skin This change in the breast makes the breasts appear to have dimples or puckers.

Sarcoma is a type of cancer that mainly occurs in the soft tissues of the body. Usually it develops in the arms and legs, and mainly in men and women over the age of fifty. Causes of soft tissue sarcoma include a weak immune system, being exposed to industrial chemicals, or sometimes prior radiation therapy to treat a different type of cancer. Some risk factors include other genetically inherited conditions (i.e., Li-Fraumeni syndrome and Retinoblastoma). Common symptoms of sarcoma include: 1. A new lump This is one of the main symptoms of soft tissue sarcoma. It can cause increased pain if it occurs next to or on a nerve or muscle. This will cause alarm in patients, but only also cause pain if the lump begins to grow on or next to a nerve or muscle. 2. Swelling This is likely to occur after the lump has formed, but not always. Usually it occurs when the tissue is formed on the arms or legs. It will look like it is occurring under the skin, unless there are skin lesions as described below. This is likely to cause pain, but not always. 3. Abdominal pain This is when soft tissue sarcoma in the abdomen.

Asthma is an inflammatory disease of the airways of the lungs and is long term in nature. Its symptoms are wheezing, coughing, tightness of the chest and shortness of breath. Depending on the patient, these symptomatic episodes can become worse at night or during exercise, or in pollen-filled, dusty or smoky environments. According to research, known triggers for asthma include environmental factors such as pollen allergies and air pollution. Other common asthma triggers may occur when exposed to pet dander or fur. Asthma has no cure, but symptoms can be reduced by the avoidance of triggers, in conjunction with doctor prescribed medications (i.e., inhalers containing corticosteroids). Asthma can also be managed by including certain foods in the diet, or by following an anti- inflammatory diet. The following foods should be included in any anti-inflammatory diet for asthma patients: 1. Fatty fish Salmon, sardines and mackerel are rich in omega-3 and other fatty acids, which help in reducing asthma symptoms. According to research and surveys, people with asthma who consume fatty fish had fewer symptoms than those who did not. 2. Avocado This fruit is very rich in L-glutathione, a substance that helps in protection of cells of the body from free radicals damage.
