Asthma Attacks

To healthy individuals, asthma may be a simple health problem but for the sufferers, its really a different thing especially when the attack is slowly setting in.

Asthma attacks happen when the air passages constrict. This may be due to allergens, air impurities, food, exercise or strenuous activities, and many others. Severe attacks are often characterized by wheezing or whistling sounds, dry cough, and breath-shortness. In an asthma attack, the air passage of the individual is clogged by mucus, the air tubes lining is swelling or inflamed. Gasping for breathe is a dreaded situation for asthmatics and so you should try to prevent the attacks as much as possible.

There are several layers in the air tube. A muscle located outside relaxes or tightens and it is responsible for controlling the air tubes opening. It is guided by the nervous system, particularly the portion for the reflexes. The muscle works like that of involuntary blinking.

You cant control how the muscles work. The outside muscle of the air tube reacts to irritants like perfume, dust, allergens, pollution, pollen, or cigarette smoke by tightening or relaxing. In the case of asthma patients, the outside muscle overreacts to the irritants, thereby causing an attack.

Aside from reacting with irritants and allergens, the muscle also reacts to other factors like exercise, cold air, pressure changes, and viral infections. When the muscle tightens, the airway narrows.

Asthma attacks are not only limited to the tightening of the muscles of the air tube but it can be caused by the inflammation of the airways lining as well. Have you ever experienced scraping your knee? If youre observant, you will notice that the knee area swells and a fluid oozes out. This fluid is made up of cells which fight the infection but it also contributes to swelling. The same thing happens in the airways. When the airways are inflamed, the lining oozes out fluid which contributes to swelling and at the same time, it obstructs the air passage.

Mucus found in the airways in not all that bad. It normally aids in the smooth flow of air into the lungs but during an asthma attack, the mucus increases and it clogs the air passage. The mucus becomes sticky making it more difficult to breathe. As long as the mucus clogs the air passage, the asthma attack will persist. You need to consult a doctor right away so that you can receive appropriate medical attention.

Keep in mind that if you leave the mucus clogs untreated, it can lead to infections. Only the doctor can give you the proper antibiotic that suits your situation. Attacks can last for a couple of minutes but for severe attacks, it can last for many hours or even days. There are intervals wherein the asthma patient will not feel any of the symptoms but it will soon return if no proper medication is given.

Doctors often conduct a breathing test to determine if the person has asthma and it is called spitometry. During the evaluation, several tests will be conducted to identify what caused the asthma attack. Once the trigger or triggers are identified, you need to stay away from them as much as possible. You have to work closely with your doctor if you want to prevent future asthma attacks. The attacks can be deadly, so dont disregard them.

What Causes Sinus Infection

Ever wondered what really causes a sinus infection? There are many possibilities and it is sometimes hard to pinpoint which one is the culprit. You could have gotten it while you are at work, out in the mall, doing a certain activity or even at home so here are some of the known causes of sinus infections.

Most sinus infections are caused by the common cold otherwise known as viral influenza. This causes congestion in the nasal passages and inhibits the drainage of the sinuses which is why it becomes inflamed.

When this happens, the nose is filled with mucus caused by the accumulation of white blood cells in the lining of the nose. This makes it difficult for the person to smell or even breathe and the only way to get rid of it is to blow it out.

Generally a common flu stays a maximum for a period of one week. After that we usually recover, but it leaves our sinuses inflamed. The nose is a very sensitive part of our body which catches a viral infection very easily.

Sinus infection can also be caused by exposure to dust particles, pollen and other irritants in the air. If there is too much of this already in the nasal passages, it prevents mucus from draining away. When these bacteria such as streptococcus pneumoniae and haemophilus influenzae end up in our upper respiratory tract and multiply, then it causes us to have a sinus infection.

You can come into contact with these every time you go outdoors or when you are inside the house especially in places where natural sunlight cannot reach. Another example is the fungus known as aspergillus that can cause problems to the immune system.

If you have asthma, you are a high risk for sinus infections because your nasal polyps inside your nose are swollen. This results in chronic sinus infections that could last for 2 weeks.

Lack of water also causes a sinus infection. This is because the mucus will thicken making it difficult for the cilia to move it through the sinuses.

Sinus infections can also happen whenever we are stressed. To prove the point, one such condition known as vasomotor rhinitis shows that stress does cause excessive swelling and mucus production.

You can also get a sinus infection by blowing your nose too much. This is because your nose will swell after blowing it too hard or too much.

Certain activities that are fun can also cause sinus infection. Traveling by air and scuba diving are very common because to much pressure in the sinuses causes bacteria to grow.

If you dont watch your kids carefully, they may inhale harmful substances or other foreign objects that introduce bacteria into the sinuses.

Certain medications are also known to cause sinus infections as a side effect because it may affect the functioning of the mucus membrane.

Lastly, although very rare, you can get a sinus infection from disease teeth because the maxillary sinus in the cheekbone becomes infected by the root of a diseased upper tooth.

There are many causes of sinus infections and it is not only bacterial or viral. Now that
