    Asthma

    Health    Asthma

    Asthma is a chronic disease that affects your airways. Your airways are tubes that carry air in and out of your lungs. If you have asthma, the inside walls of your airways become sore and swollen. That makes them very sensitive, and they may react strongly to things that you are allergic to or find irritating. When your airways react, they get narrower and your lungs get less air.

    Symptoms of asthma include

    • Wheezing
    • Coughing, especially early in the morning or at night
    • Chest tightness
    • Shortness of breath

    Not all people who have asthma have these symptoms. Having these symptoms doesn't always mean that you have asthma. Your doctor will diagnose asthma based on lung function tests, your medical history, and a physical exam. You may also have allergy tests.

    When your asthma symptoms become worse than usual, it's called an asthma attack. Severe asthma attacks may require emergency care, and they can be fatal.

    Asthma is treated with two kinds of medicines: quick-relief medicines to stop asthma symptoms and long-term control medicines to prevent symptoms.

    Questions - Asthma

    Asthma is a disease that causes the airways of the lungs to become swollen and narrow leading to shortness of breath, chest tightness and coughing. There are different types of medications for treating asthma and as such, each medication has different side effects, therefore weight gain from an asthma inhaler depends on which medication is found in the inhaler. Commonly prescribed asthma inhalers like Albuterol and Levalbuterol do not list weight gain as an adverse effect of using this medication. Another common combination medication, Advair consisting of a steroid and a long-acting beta agonist, does not list weight gain as a common side effect, but it has been reported by some patients with postmarketing experience.
    
    Asthma medications include long-term and quick-relief medicines; long-term medicines help to prevent symptoms, while quick-relief medicines are used as rescue medication for attacks of shortness of breath or wheezing. Long-term medications include agents like steroids and long-acting beta-agonists. Quick-relief medications include agents like short-acting inhaled bronchodilators and oral corticosteroids.

    Yes, Asthma inhalers are considered to be safe for pregnant women. But, it is recommended to be taken under doctor's supervision only. Drugs which are used as asthma inhalers are Salbutamol, Beclomethasone, Fluticasone and many more. FDA has specified anti-asthma drugs in Pregnancy category C which specifies that there was the fetal harm in animals administered with the drugs in the first trimester of pregnancy but there is no adequate data for human studies that have demonstrated anti-asthma drugs to be safe for use in women in any trimester of pregnancy.
    
    Salbutamol is a short-acting sympathomimetic agent that helps to open the large airways in the lungs. It is used to treat asthma, chronic obstructive pulmonary disease (COPD), exercise-induced bronchoconstriction, and high blood potassium levels. It also stimulates beta-1 adrenergic receptors which increase the rate of myocardial contraction.
    
    Studies have demonstrated that Salbutamol use in pregnant females may delay preterm labor. So, caution is recommended before using it for bronchospasm in pregnant women as it has possible interference with uterine contractility. In post-marketing experience, various congenital anomalies, cleft palate, and limb defects have been reported in the infants of pregnant women being treated with albuterol.
    
    Women taking asthma inhalers are advised to notify their gynaecologist if they become pregnant or intend to become pregnant.
