Asthma - Causes, Symptoms, Diagnosis & Treatment

There are many potential causes of asthma, including genetics, allergies, and air pollution. Symptoms can vary from mild shortness of breath to severe attacks that make it difficult to breathe. Asthma is diagnosed with a physical exam and by testing lung function. Treatment typically includes a combination of medications and lifestyle changes.

Asthma is a chronic lung disease that inflames and narrows the airways. Symptoms include wheezing, coughing, chest tightness, and shortness of breath. Asthma is caused by environmental factors, such as smoke, dust, and pet dander, and by genetic factors. It is diagnosed with a medical history and physical exam and may be confirmed with tests that measure how well you breathe. Treatment includes medications to open the airways and control inflammation and avoid triggers. Symptoms of asthma include wheezing, chest tightness, shortness of breath, and coughing.

The cause of asthma is not known, but it is thought to be caused by a combination of environmental and genetic factors. Risk factors for asthma include exposure to cigarette smoke, air pollution, pets, and dust mites. Asthma is diagnosed based on your symptoms and by doing a breathing test called spirometry. Treatment for asthma includes using medication (such as inhalers) to open the airways and prevent attacks, as well as avoiding triggers.

Common symptoms of asthma include coughing, wheezing, chest tightness, and shortness of breath. These symptoms can vary in intensity and may come and go. Asthma is typically diagnosed based on a person's symptoms and medical history. Treatment for asthma includes medications such as bronchodilators and corticosteroids, as well as lifestyle changes such as quitting smoking and avoiding triggers.

The main symptom of asthma is wheezing. This is a high-pitched sound that you hear when you breathe out. Other symptoms include chest tightness, shortness of breath, and coughing. Asthma can occur at any age but it most often starts during childhood or early adulthood. There is no cure for asthma, but it can be controlled with medicines and by avoiding things that trigger an attack. Treatment options include bronchodilators (drugs that open up the airways), and anti-inflammatory drugs.

Asthma has many potential causes, including genetics, allergies, and exposure to environmental factors such as air pollution. Symptoms of asthma include wheezing, chest tightness, and shortness of breath. A diagnosis of asthma is made based on a person's medical history and a physical examination. There is no one-size-fits-all treatment for asthma; it is typically managed with a combination of medications and lifestyle changes. Some people with asthma also require regular use of an inhaler to keep their symptoms under control. Living with asthma can be challenging at times, but most people can lead full and active lives if they take the necessary steps to manage their condition

The cause of asthma is not known, but it is thought to involve both environmental and genetic factors. Cigarette smoke, air pollution, dust mites, animal dander, and cockroaches can all trigger asthma attacks. Diagnosis of asthma is made based on medical history and physical examination. Lung function tests (spirometry) are also often done. Treatment includes medications such as bronchodilators to open the airways and steroids to reduce inflammation, as well as lifestyle changes such as quitting smoking and avoiding triggers

There is no one-size-fits-all answer to this question, as the causes and symptoms of asthma can vary from person to person. However, some of the most common causes of asthma include exposure to allergens (such as pet dander, dust mites, or pollen), respiratory infections, air pollution, and smoke. Symptoms of asthma can include coughing, wheezing, chest tightness, and shortness of breath. If you are experiencing any of these symptoms, it's important to see a doctor for diagnosis and treatment. Treatment options for asthma may include medications such as bronchodilators and corticosteroids, along with lifestyle changes such as avoiding triggers and exercising regularly.

There is not one answer to this question as asthma can be caused by a variety of things, including allergies, genetics, smoke, and fumes. However, some of the most common symptoms of asthma include coughing, wheezing, chest tightness, and shortness of breath. If you are experiencing any of these symptoms on a regular basis, it is important to see a doctor for diagnosis and treatment

Asthma is characterized by airway hyper-responsiveness, mucous production, and remodeling. It is a common disease, affecting about 300 million people worldwide. The cause of asthma is not fully understood, but it is believed to be caused by a combination of environmental and genetic factors. Symptoms of asthma include coughing, wheezing, chest tightness, and shortness of breath. The diagnosis of asthma is based on symptoms and the results of pulmonary function tests. Treatment for asthma includes medications such as bronchodilators, corticosteroids, and leukotriene modifiers, as well as lifestyle modifications such as quitting smoking and avoiding triggers.

Role of Nutrition in Disease Prevention: How Food Choices Shape Long-Term Health

Disease prevention is no longer limited to vaccinations and medical screenings. Modern healthcare increasingly recognises nutrition as one of the most powerful tools for preventing illness before it begins. The role of nutrition in disease prevention is especially important in India, where lifestyle-related diseases account for a large share of premature illness and mortality.

According to the Indian Council of Medical Research (ICMR) and the National Family Health Survey (NFHS-5), poor dietary patterns contribute significantly to rising cases of diabetes, heart disease, obesity and hypertension. Unlike genetic factors, nutrition is a modifiable risk factor, meaning everyday food choices can actively protect health.

Why Nutrition Is Central to Disease Prevention

1. Nutrition regulates metabolic health

Balanced diets help maintain:

healthy blood sugar levels
optimal cholesterol balance
stable blood pressure

Disruption in these systems increases disease risk.

2. Nutrition strengthens immunity

WHO highlights that immune function depends heavily on adequate intake of vitamins, minerals and protein.

3. Nutrition controls inflammation

Chronic low-grade inflammation is linked to most lifestyle diseases. Diets rich in whole foods reduce inflammatory markers.

Major Diseases Influenced by Nutrition

Diabetes and Prediabetes

Excess refined carbohydrates and sugar drive insulin resistance.

Preventive nutrition focuses on:

whole grains
fibre-rich vegetables
adequate protein
controlled portion sizes

ICMR data shows that dietary modification can delay or prevent type 2 diabetes in high-risk individuals.

Cardiovascular Disease

Heart disease remains a leading cause of death in India.

Nutrition impacts:

cholesterol levels
blood pressure
arterial inflammation

Diets low in trans fats and high in fibre significantly reduce cardiovascular risk, as confirmed by WHO and Lancet studies.

Obesity

Obesity increases the risk of multiple chronic diseases.

Preventive nutrition addresses:

calorie density
food quality
satiety regulation

NFHS-5 reports a steady rise in overweight and obesity across age groups.

Hypertension

High sodium intake and low potassium intake contribute to high blood pressure.

Preventive dietary strategies include:

reducing processed foods
increasing fruits and vegetables
maintaining mineral balance

Certain Cancers

Diet influences cancer risk through:

antioxidant intake
fibre consumption
reduced exposure to carcinogenic compounds

WHO estimates that a significant percentage of cancers are preventable through diet and lifestyle changes.

Key Nutrients That Support Disease Prevention

Fibre

Supports gut health, blood sugar control and cholesterol reduction.

Protein

Essential for muscle health, immune function and metabolic balance.

Healthy Fats

Omega-3 fats reduce inflammation and protect heart health.

Micronutrients

Iron, zinc, vitamin D and B vitamins are essential for metabolic and immune regulation.

NFHS-5 highlights widespread micronutrient deficiencies in India, increasing disease vulnerability.

Role of Gut Health in Prevention

The gut microbiome plays a major role in:

immune regulation
inflammation control
nutrient absorption

Fermented foods and fibre-rich diets support healthy gut bacteria, strengthening disease resistance.

Why Preventive Nutrition Works Best Early

Nutrition is most effective when applied:

before disease onset
during pre-disease stages
alongside regular health screening

Once disease progresses, nutrition remains supportive but may not reverse damage fully.

Nutrition vs Medication in Prevention

Medication treats disease; nutrition reduces risk.

WHO and NITI Aayog emphasize that:

preventive nutrition reduces disease incidence
lifestyle modification lowers healthcare burden
early nutrition changes reduce dependency on long-term medication

Both approaches work best when combined appropriately.

Workplace and Community Role in Preventive Nutrition

Structured nutrition programs at workplaces and communities:

improve awareness
support behaviour change
reduce population-level disease burden

Lancet studies show that group-based nutrition interventions improve long-term adherence.

Common Myths About Nutrition and Disease Prevention

Myth 1: Supplements replace healthy food

Whole foods provide better long-term protection.

Myth 2: Prevention requires extreme diets

Consistency matters more than restriction.

Myth 3: Nutrition only matters after diagnosis

Early nutrition is most effective before disease develops.

Building a Preventive Nutrition Routine

Effective preventive nutrition includes:

regular meals
diverse food groups
portion awareness
minimal processed foods
hydration

Small daily choices compound into long-term health benefits.

Long-Term Impact of Preventive Nutrition

Consistent healthy eating leads to:

reduced disease risk
improved energy and productivity
better immune resilience
lower healthcare costs
improved quality of life

NITI Aayog identifies nutrition as a cornerstone of sustainable healthcare systems.

Conclusion

Understanding the role of nutrition in disease prevention empowers individuals to take control of their health long before illness develops. Balanced, consistent nutrition reduces inflammation, supports immunity and protects against chronic diseases that burden India’s healthcare system. Preventive nutrition is not about short-term fixes but about building lifelong habits that support health, resilience and longevity.
