HayfeverHayfever is an allergy to pollens - the male reproductive parts of plants - from grasses and trees. When they come into contact with the tissue inside the nose, they trigger an immune reaction that can cause congestion, sneezing, itching, and a runny nose. It is more common during the summer when the levels of pollen are highest. It can also be triggered by moulds, which are likely to be found in rainy or humid areas.

HeartburnWhat the English have called dyspepsia or heartburn is actually esophageal reflux. The problem is caused by the backflow of stomach acid upward into the lower esophagus. In normal digestion, the valve that separates the esophagus and stomach, the lower esophageal sphincter (LES), opens to allow food to pass into the stomach and then closes to prevent the food and acidic stomach juices from flowing back up. Esophageal reflux occurs when the LES relaxes more often than it should and/or at inappropriate times causing the stomach contents to back up. Sometimes, particularly in obese people, the opening through the diaphragm that allows the esophagus to pass from the chest to the abdomen becomes large. This is called a hiatal hernia and may result in esophageal reflux. The stomach has a lining that protects it from the effects of the acid and because the esophagus lacks this lining, the stomach acid that refluxes will cause pain, inflammation (esophagitis), and damage. Excessive backflow of the stomach contents into the esophagus causes gastroesophageal reflux disease (GERD). Untreated GERD can result in precancerous changes called Barrett's esophagus.

Herpes Simplex/ZosterThe herpes simplex virus (HSV) can cause blisters and sores almost anywhere on the skin. These sores usually occur either around the mouth and nose, or on the genitals and buttocks. HSV infections can be very annoying because they can periodically reappear. The sores may be painful and unsightly. For chronically ill people and newborn babies, the viral infection can be serious, but rarely fatal. |

Hyperthyroid: Excess of thyroid hormone resulting from an overactive thyroid gland (or taking too much thyroid hormone). Symptoms can include increased heart rate, weight loss, depression , and cognitive slowing. Treatment is by medication, the use of radioactive iodine, thyroid surgery, or reducing the dose of thyroid hormone. MedicineNet.com |
HypoglycemiaHypoglycemia literally means "low blood sugar" and is often mistaken for a disease when it is actually a symptom. Ingested sugars and carbohydrates trigger a release of the hormone insulin from the pancreas. Insulin helps the body turn sugars into energy and stored fats. In some people, the amount of insulin released is too high for the amount of carbohydrates ingested, resulting in too much sugar being burned up too quickly. A net loss of blood sugar results. In hypoglycemia attacks, there is too much insulin and not enough blood sugar, causing fatigue, weakness, loss of consciousness, and even death. (Life extension Foundation)

Hypothyroidism is a condition in which the body lacks sufficient thyroid hormone. Since the main purpose of thyroid hormone is to "run the body's metabolism", it is understandable that people with this condition will have symptoms associated with a slow metabolism. Over five million Americans have this common medical condition. In fact, as many as ten percent of women may have some degree of thyroid hormone deficiency. EndocrineWeb.com |
