Swine flu is a disease that affects pigs and is a highly contagious type of respiratory disease caused by a version of the influenza A virus. Typically, swine flu is of the subtype designated as H1N1, and this is also the subtype that is currently affecting humans.

H1N1 Swine Flu Virus

Although swine flu normally affects pigs, it can sometimes jump to a different species, which is what has happened with humans. Symptoms of swine flu are, on the whole, very similar to normal seasonal influenza outbreaks in humans and can range between no symptoms at all or very mild symptoms, to severe and even fatal pneumonia. Because these symptoms are similar to the normal flu symptoms, swine flu is almost impossible to distinguish from normal flu, unless specifically looked for by a doctor.

Humans can catch swine flu either by contact with pigs that are infected, which is the most common way, and contact with humans that are infected, which is less common. For human to human infection to occur, very close contact needs to occur between the two parties.

Swine Flu Symptoms

The symptoms of swine flu in humans is very similar to normal influenza symptoms, as mentioned above, and these can be aches, chills, coughing, diarrhea, headache, sore throat, fever, fatigue and vomiting. Most previous cases of swine flu in humans has cleared up without any medical assistance, but there are a couple of drugs that are successful in treating the condition – adamantanes and inhibitors of influenza neuraminidase.

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.

Drug allergies are adverse reactions to medication drugs and these reactions can be separated into three groups. First are those not actually related to the drug in question at all, but are coincidental and attributed to other mitigating factors associated with the illness or disease. Second are common predictable reactions like side effects related to taking other medication at the same time, or having an overdose. The third is unpredictable and uncommon reactions of which quite a few are allergic reactions that typically involve the immune system, being either immediate or delayed in reaction.

Allergic reactions can vary greatly from simple, slight rashes to very severe anaphylactic reactions of the immune system. Some drugs that can cause allergic reactions include heart drugs such as ACE inhibitors, antibiotics like penicillin, anesthetic drugs such as muscle relaxants, morphine, aspirin like drugs such as ibuprofen, chemotherapy drugs, antiseptics like iodine, vaccines such as tetanus, and colorings or preservatives in certain medications.

Reactions usually occur within one hour of taking the medication and can involve a measle-like rash that is very itchy. Some life threatening reactions may involve skin blistering with peeling accompanied by fever.

Common Allergic Reactions

Treatments of various drug allergic reactions involve the immediate withdrawal of the offending drug and then the administration of an antihistamine medicine. In severe allergic reactions, adrenaline and steroids may be used to save a life.
