Cholesterol is a lipid, or fat, of the body, and it is this along with another lipid called triglyceride that are vital building blocks of a cell. They are also used in the production of hormones as well as producing energy. Cholesterol is mainly produced in the liver, but it can also be ingested with certain foods.

There are two types of cholesterol and just to keep things simple, these can be classed as the good sort (high-density lipoprotein or HDL) and the bad sort (low-density lipoprotein or LDL). The HDL is effective in reducing cholesterol by transporting it back to the liver from where it is eliminated, whereas the LDL can contribute to certain diseases associated with the heart or blood circulation. HDL levels can be raised through exercise and LDL lowered by eating less saturated fat or sometimes with the aid of medication.

Cholesterol levels can be hereditary as well as being influenced by which part of the world the sufferer lives in. Northern Europeans have higher levels than their Southern counterparts, for example, and a much higher level than Asian people.

High Cholesterol

There are no symptoms of having high cholesterol and it is only one factor of many that can contribute to hardening of the arteries. Other factors include smoking, diet, alcohol intake, exercise and body weight. If going on a cholesterol lowering diet doesn’t help to reduce the levels, then medication will be required to assist the process.

Obesity occurs when excess weight causes health problems.  People with obesity usually have a BMI or Body Mass Index greater than 30.  Weight gain is usually caused when energy (calorie) intake is more than calories burnt.  There are many risks for people with obesity as it can contribute to an increase in a variety of diseases such as heart disease, high blood pressure, diabetes, and some forms of cancer.  Some people are more prone to weight gain than others and this can be down to genes, however, most people find that obesity is a factor of lifestyle and eating behaviors.

Many people eat when they are depressed, lonely, anxious, stressed or just when they are bored.  Obesity is also linked to a lack of physical exercise.  In today’s day there seems to be more and more examples of children showing signs of obesity at an alarmingly young age.  Schools, parents and government organizations seem to be recognizing the need to encourage children to eat more healthily and to support exercise programs.

Obesity

There is a higher amount of processed, cheaper foods available on the market today which are higher in sugar, salt, and fat which contributes to the increase in obesity levels among young people.  Coupled with the trend for video games and increased numbers of TV channels it is no surprise that more and more young people are being diagnosed with obesity every day.

Diet and exercise are the most important factors when preventing obesity.  In order to lose weight people need to reduce daily calories and partake in at least 20 – 30 minutes of exercise daily.  Increased fruit and vegetables can help to feel full and reduce the chance of reaching for sugary foods which contain more fat.

Psoriasis is a skin condition which can start at any age but usually starts after puberty. Skin cells are produced by the body and as new cells are produced the older ones on the outer layer of the skin die and flake off.  This process usually takes between 21 to 28 days, but for someone with psoriasis, the process is accelerated and can occur in as little as six days.  This results in an excess of skin cells building up on the surface of the skin which are then shed easily.  Psoriasis can occur anywhere on the body and appears as red, crumbling patches of skin.  The most common places on the body where psoriasis is found are the scalp, knees, elbows or lower back.

There are many treatments for psoriasis but no cure.  Symptoms can be mild in one person but extremely severe in others and can cause distress.  Psoriasis can be mild at some times and then flare up.  There are different types of psoriasis and most people only have one type at a time but find that one type can develop into another type.  The most common types of psoriasis are plaque psoriasis, nail psoriasis, guttate psoriasis, scalp psoriasis and inverse psoriasis.  There are rarer forms of psoriasis called pustular psoriasis and erythrodermic psoriasis.  Pustular psoriasis causes pus-filled blisters to appear on the skin, while erythrodermic psoriasis causes a rash to appear all over the body and can result in the body losing proteins and fluids.

Psoriasis

There are some factors which can trigger a flare up of psoriasis symptoms such as smoking, stress, alcohol, and some medicines.  There are three types of treatment for psoriasis and these are creams and ointments, lights which the skin can be exposed to and oral or injected medication.
