Jaundice is a common condition in newborn babies and generally results in a yellowish discolouration of the skin and the eyes due to increased bilirubin levels in blood. Jaundice may also arise due to insufficient breast-feeding, substances produced in mother’s milk that increases the baby’s bilirubin levels or due to blood group mismatch between the mother and baby. It is generally a mild condition and improves on its own within 1 or 2 weeks. In rare cases, it may be dangerous leading to deafness or brain damage. Asthma Asthma is a condition affecting the lungs in which air passages narrow, swell and produce extra mucus. This makes breathing difficult and can often lead to coughing, wheezing, chest tightness and shortness of breath. Asthma can’t be cured but it’s symptoms can be controlled. Since asthma changes over time, it is important to track allergens and irritants and work with your doctor to adjust or change treatment as needed. Atrial Fibrillation Atrial Fibrillation(AF) is abnormal, irregular and often rapid heart rate that leads to heart palpitations, fainting, shortness of breath and chest pain. During AF, heart’s two upper chambers beat irregularly and out of sync with heart’s two lower chambers. AF can lead to formation of blood clots in heart that may circulate to other organs and cause blockage of blood flow. AF is treated with medications to slow the heart rate and alter heart’s electrical system.
