Hypertension can wreck havoc on many body organs. Its effects on the heart are especially damaging. High blood pressure and heart disease are closely connected.

Moderate to high blood pressure significantly increases the load on the left side of the heart. Arterioles are often diseased or constricted, which increases resistance to blood flow. When this happens, the heart has to work much more to pump blood into the arterial system including the aorta.

When any muscle is overused, it tends to increase in size and bulk. The heart muscles react the same way. An enlarged heart is a sign of trouble.

Heart enlargement can be detected in several ways. A chest x-ray can reveal it. So can an electrocardiogram or even a physical examination.

In many high blood pressure patients, the walls of the left ventricle thicken. This increases the workload on the heart. Eventually, the heart falters and the left side of the heart no longer pumps blood adequately.

When this happens, major organs and tissues of the body are denied sufficient blood supply. The affected person becomes lethargic and weak.

Because of the higher pressure in the left ventricle, blood from the lungs cannot drain into the top compartment of the heart (the atrium). As a result, the lung tissues get congested which brings on bouts of breathlessness and coughs.

The patient may have a dry cough or even frothy phlegm with blood stains in it. This is a very scary experience to the sufferer and onlookers. In an acute attack, it seems to the patient that he or she is choking to death.

Breathlessness due to heart problems may be first noticed during prolonged physical exertion. If the condition has progressed further, breathlessness may occur even while resting.

Nothing can be more upsetting than getting turned down by a the opposite sex especially when your suffering from depression. Be rest assured this is not the end of the world. While dating can be fun it can also help us out tremendously when we are feeling depressed. Having someone to talk to and be with will naturally lift your spirits up. But remember to keep cool and follow these general guidelines when dating while depressed.

Remember you may feel exhilerated at the first date, but as time goes on and you continue to date the person as things become routine you may start to feel depressed. Remember to always be doing something, The same routine over and over again is boring, unless of course your perfectly content with boredom.

Okay, we havent got to the part about asking the person out! That by far is the hardest part for anyone to do, especially if you are a person who is less socially active. But don’t dispair, it’s easier than you think. Think about it this way, do you get fearful when your calling up dear old gramma on the phone to check how she is doing? No! And I highly doubt she would reject you either. Just work up the courage, you can do it. Rehearse what you are going to say at first, and get it down so its fluid like. Don’t be depressed if you get rejected. The best of us all get rejected at times.

Rapid onset-fast acting insulin

Rapid onset-fast acting insulin always looks clear. It is fast acting and starts to work within one to 20 minutes. It peaks about one hour later and lasts from three to five hours. When you use this type of insulin, you must eat immediately after you inject.

The two rapid onset-fast acting insulin types currently available are:

1. NovoRapid (Insulin Aspart)
2. Humalog (Lispro).

Short acting insulin

Short acting insulins always look clear. They begin to lower blood glucose levels within half an hour, so you need to have your injection half an hour before eating.

Short acting insulin has a peak effect at two to four hours, and lasts for between six and eight hours. Short acting insulin types currently available include:

1. Actrapid
2. Humulin
3. Hypurin Neutral (bovine – highly purified beef insulin).

Intermediate acting insulin

Intermediate acting insulins always look cloudy. They have either protamine or zinc added to delay their action. These insulins begin to work about 90 minutes after you inject, peak at four to 12 hours, and last for 16 to 24 hours.

Intermediate acting insulins currently available include:

1. With protamine added Protaphane, Humulin NPH and Hypurin Isophane (bovine).

AIDS is an acronym for Acquired Immunodeficiency Syndrome it causes a destruction of the immune system. It is the most advanced stage of the HIV virus (HIV stands for Human Immunodeficiency Virus). AIDS is defined by the Centers for Disease Control and Prevention (CDC) as the presence of a positive HIV antibody test and one or more of the illnesses known as opportunistic infections.
The HIV virus, type 1 or 2 is widely known to be the cause of AIDS. HIV breaks down and attacks your T cells so your body is unable to defend itself against different infections. The HIV virus also attacks your peripheral nervous system, this causes nerve and muscle pain, especially in the feet, legs, and hands.
HIV is spread through direct contact with semen or blood of an individual that is infected. This can be transferred in many ways the most common is unprotected sexual intercourse. Other means of infection are infected blood transfusions, mother to infant (at time of birth, or through breast milk), sharing needles with an infected person, and rarely a healthcare worker that gets pricked with an infected needle.

Often people who are infected with HIV have few symptoms and in some cases there are none. Other times, symptoms of HIV are confused with other illnesses such as the flu. This may be severe, with swollen glands in the neck and armpits, tiredness, fever and night sweats. This is where as much as 9 out of 10 of the infected individuals will develop AIDS. At this point the person may feel completely healthy and not even know that he/she has the virus. The next stage begins when the immune system starts to break down and the virus becomes more aggressive in damaging white cells. Several glands in the neck and armpits may swell and stay swollen for an extended period of time without any explanation. As this disease progresses boils or warts may spread over the body. They may also feel tremendously tired, night sweats, high fevers, chronic diarrhea, and they may lose a considerable amount of their body weight. Most cases have shown thrush as a symptom as well. At this point the person is in the final stages of HIV–AIDS. Severe chest infections with high fever are common and survival rate is above 70% but decrease with each recurrence.
