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.

An anxiety disorder can loosely be described as a condition where feelings of anxiety can get in the way of normal, everyday life. Many things can cause or even be classed as an anxiety disorder, and these can include phobia, obsessive compulsive disorder (OCD), post traumatic stress disorder (PTSD), panic attacks and generalized anxiety disorder (GAD).
Anxiety attacks can be caused by a variety of conditions, both mental and physical. On the mental side of things, problems such as alcohol dependence, depression, substance abuse (including drugs, nicotine and caffeine) and medicine withdrawal can all cause anxiety. Physically, a person could be affected due to illnesses or cosmetic reasons such as appearance. It can also be brought on by stress due to traumatic events like bereavement.

Anxiety
There are some physical symptoms attributed to being anxious and these occur due to the body’s natural “fight or flight” response due to the release of adrenaline. These can include dry mouth, diarrhoea, tightness in the chest, rapid heartbeat, dizziness, shortness of breath, shaking, the need to urinate more frequently and swallowing difficulty.
A few psychological symptoms associated with anxiety include uneasiness, insomnia, irritability, tiredness, lack of concentration and a fear of “going mad”. Sometimes, when anxiety disorders and other conditions such as schizophrenia, depression or bipolar disorder occur together, suicide or self-harm can often be the regrettable outcome.

Rotavirus infection affects the stomach and intestines in children with symptoms including diarrhea and vomiting. Most cases of the rotavirus infection are mild and usually clear up without medical intervention within a few days but some children, especially toddlers under the age of two, can be at risk of dehydration so it is essential to keep them hydrated with plenty of fluids.
The rotavirus infection is spread by infected people who haven’t washed their hands properly after going to the toilet. This can cause tiny amounts of infected feces being passed on to the child. Small amounts of these infected feces can also be carried in the air resulting in the child inhaling them. Most children will have contracted the rotavirus infection by the age of five. The rotavirus infection is more common during the winter and spring and it is usually common for the first virus to be the worst as after that the child will have built up some immunity. It is for this reason that the rotavirus is rare in adults.

Rotavirus Infection
The rotavirus is extremely contagious in children and can even infect children who have already had the infection due to full immunity not being built up. It is a good idea to isolate an infected child for a period of at least 48 hours after they have stopped having diarrhea and vomiting.
Symptoms of the rotavirus infection include rapid onset of diarrhea and vomiting and also occasionally a high temperature of 38C or above however it is important to recognize the signs of dehydration as this can occur if not enough fluids are taken. Signs of dehydration include weakness, rapid breathing, little or no urine, or dry mouth and eyes.
The most important thing to do for a child with the rotavirus infection is to keep them hydrated and the infection will usually pass within a few days.
