The simple description of asthma is that it is a condition that affects the bronchioles in the lungs. Every now and again these tiny airways that are the bronchioles constrict in individuals who have asthma, and it is this that causes the typical symptoms of the condition. How much these tiny airways narrow, and the duration of each “attack” varies a great deal.

Asthma is actually caused by an inflammation in the bronchioles but it hasn’t been recognized up to now why this actually happens. It is this inflammation that affects the muscles that surround the bronchioles and causes them to constrict. This constriction then makes it difficult for air to enter and leave the lungs.

Asthma

Asthma can manifest itself at any age, but usually starts during childhood. In western society, an average of one in ten children and one in twenty adults suffer from asthma. Although the condition does run in families, there are still plenty of people who have it while no other members of their family are affected.

The most common types of symptoms suffered are coughing and wheezing accompanied by breathlessness and a tightening of the chest. These symptoms can also vary from mild to severe in different individuals.
Nearly all asthma sufferers are treated with inhalers and these are small devices that deliver tiny doses of drugs directly into the airways, which relieves irritation in turn helping the airways to expand, making it easier to breathe.

The heart is a pump that is designed to force blood through the body and as with any type of pump, it works by generating pressure. In the body, the blood is pumped through the arteries to all major organs, but if there is too much pressure it can put a strain on the heart itself or the arteries, causing all sorts of problems.

Blood pressure is dependent on two things. The first is the force with which the heart pumps the blood around the body, and the second is the narrowness of the arteries. Hypertension happens when the blood is forced with increased pressure through the arteries.

When blood pressure is measured, it is done so using two numbers, an example being 120 over eighty. The first number listed is the systolic blood pressure which is the maximum pressure exerted on the arteries when the heart beats, and the second number listed is the diastolic blood pressure, or the minimum amount of pressure on the arteries when the heart is relaxed. The example above is of a normal blood pressure reading.

Blood pressure can be considered high when the systolic blood pressure reading is constantly above 160, and/or the diastolic blood pressure reading is above 100. One of the biggest problems with high blood pressure though, is the fact that it doesn’t always cause any symptoms meaning it may go unnoticed until a later complication such as a heart attack or stroke.

Other complications arising from high blood pressure can be an aneurysm, heart failure, eye damage, kidney failure or atherosclerosis, which is the narrowing of the arteries. Some factors that could contribute to high blood pressure include hereditary reasons, obesity, kidney disease, diabetes, excessive salt intake, lack of exercise and high intake of alcohol.

High Blood Pressure

Migraines are throbbing headaches that are normally very intense, occurring in just one half of the head. They can affect people of all ages and their cause is unknown. What is known is that during a migraine attack, blood vessels located in the brain dilate. This dilation causes the blood vessels to draw in on each other which stimulate the nerve endings near to these blood vessels. It is this that is thought to cause the pain.

Migraine

Migraines are fairly common occurrences, affecting nearly 20% of women and 6% of men during their lifetimes. Triggers for the migraine attack can vary, but some people are very aware that eating certain foods such as chocolates, cheese or citrus fruits can bring on an attack. Some other things that have been known to trigger migraines include anxiety, stress, exercise, loud noise, bright lights, traveling and the contraceptive pill. Many women appear to have attacks on or around the time of the menstrual periods.

When people describe migraines, they are commonly associated with headaches of varying degrees. These can include headaches occurring in bouts of approximately four to 72 hours; headaches on one side of the head; headaches throb and get worse with physical activity; nausea accompanied by vomiting; and other symptoms associated with sensitivity to light.

Migraines are treated by using painkillers. Which type depends on the severity and length of bouts being suffered.
