&lt;h2&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Alpha-1 Antitrypsin Deficiency (AATD): Symptoms, Causes, Diagnosis &amp;amp; Treatment&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;hr /&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Alpha-1 antitrypsin deficiency (AATD) is a &lt;strong&gt;genetic condition&lt;/strong&gt; that can affect the &lt;strong&gt;lungs, liver, skin, and blood vessels&lt;/strong&gt;. It is inherited and may run in families, although not everyone with AATD develops symptoms. Even within the same family, the condition can vary significantly in severity and presentation.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;AATD occurs when the body does not produce enough of the protective protein alpha-1 antitrypsin (AAT), or when the protein is produced incorrectly. Over time, this can lead to serious complications such as &lt;strong&gt;chronic obstructive pulmonary disease (COPD)&lt;/strong&gt;, &lt;strong&gt;liver disease&lt;/strong&gt;, and, in rare cases, skin or vascular disorders.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Although there is &lt;strong&gt;no cure&lt;/strong&gt;, early diagnosis and appropriate medical care can significantly reduce complications and improve quality of life. Many people with AATD &amp;mdash; especially those who never smoke &amp;mdash; can live a near-normal lifespan.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;h2&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;What Is Alpha-1 Antitrypsin?&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;hr /&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Alpha-1 antitrypsin is a protein produced in the &lt;strong&gt;liver&lt;/strong&gt; and released into the bloodstream. Its primary role is to protect lung tissue from damage caused by enzymes released during inflammation, particularly &lt;strong&gt;neutrophil elastase&lt;/strong&gt;.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;In people with AATD, genetic changes cause:&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Reduced production of AAT, or&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Production of a misfolded AAT protein that becomes trapped in the liver&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;This dual problem explains why AATD can damage &lt;strong&gt;both the lungs and the liver&lt;/strong&gt;.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;h2&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Symptoms of AATD&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;hr /&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Symptoms depend on which organs are affected and how severe the deficiency is. Many people remain symptom-free for years.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Symptoms typically appear in &lt;strong&gt;adults over 30&lt;/strong&gt;, but &lt;strong&gt;children and infants&lt;/strong&gt; may show signs of liver disease.&lt;/span&gt;&lt;/p&gt;
&lt;h3&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Lung Symptoms&lt;/strong&gt;&lt;/span&gt;&lt;/h3&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;A lack of functioning AAT leaves the lungs vulnerable to environmental damage.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Common symptoms include:&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Shortness of breath&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Wheezing&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Chronic cough with mucus&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Reduced exercise tolerance&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Fatigue&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Recurrent chest infections&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Smoking dramatically accelerates lung damage and is the &lt;strong&gt;single most important risk factor&lt;/strong&gt; for early disease.&lt;/span&gt;&lt;/p&gt;
&lt;h3&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Liver Symptoms&lt;/strong&gt;&lt;/span&gt;&lt;/h3&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Misfolded AAT protein can build up in the liver, causing inflammation and scarring.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Symptoms may include:&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Yellowing of the skin or eyes (jaundice)&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Unexplained weight loss&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Poor appetite&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Swelling of the abdomen or legs&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Severe fatigue&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Vomiting blood or blood in stools&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;In infants, liver disease may present as persistent jaundice, pale stools, or dark urine.&lt;/span&gt;&lt;/p&gt;
&lt;h3&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Skin Symptoms (Rare)&lt;/strong&gt;&lt;/span&gt;&lt;/h3&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;AATD can cause &lt;strong&gt;panniculitis&lt;/strong&gt;, an inflammatory condition of the fat beneath the skin.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Signs include:&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Painful lumps under the skin&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Red or hot patches, often on the legs or abdomen&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Oily fluid leaking from broken skin lesions&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;h3&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Blood Vessel Involvement (Very Rare)&lt;/strong&gt;&lt;/span&gt;&lt;/h3&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Inflammation of blood vessels (&lt;strong&gt;vasculitis&lt;/strong&gt;) may occur.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Possible symptoms:&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Fever&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Generalised aches&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Fatigue&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Weight loss&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;h2&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Causes of Alpha-1 Antitrypsin Deficiency&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;hr /&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;AATD is caused by variants in the &lt;strong&gt;SERPINA1 gene&lt;/strong&gt;, which controls AAT production.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Each person inherits:&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;One gene copy from their mother&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;One gene copy from their father&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;h3&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Common Genetic Variants&lt;/strong&gt;&lt;/span&gt;&lt;/h3&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;&lt;strong&gt;MM&lt;/strong&gt; &amp;ndash; Normal (lowest risk)&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;&lt;strong&gt;MS / MZ&lt;/strong&gt; &amp;ndash; Carrier (moderate risk)&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;&lt;strong&gt;ZZ&lt;/strong&gt; &amp;ndash; Severe deficiency (highest risk)&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;More than &lt;strong&gt;120 genetic variants&lt;/strong&gt; have been identified. Having two abnormal variants leads to AATD, while one abnormal variant makes a person a &lt;strong&gt;carrier&lt;/strong&gt;.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;h2&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Risk Factors&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;hr /&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Factors that increase the likelihood of complications include:&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Family history of AATD&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Smoking or passive smoke exposure&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;COPD or emphysema at a young age&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Chronic liver disease&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Obesity and diabetes&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Obstructive sleep apnoea&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;AATD is most common in people of &lt;strong&gt;Northern European descent&lt;/strong&gt;, but it affects individuals worldwide and is &lt;strong&gt;frequently underdiagnosed&lt;/strong&gt;.&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;h2&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Complications&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;hr /&gt;
&lt;h3&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Lung Complications&lt;/strong&gt;&lt;/span&gt;&lt;/h3&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;AATD significantly increases the risk of:&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;&lt;strong&gt;Emphysema&lt;/strong&gt;&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;&lt;strong&gt;Chronic bronchitis&lt;/strong&gt;&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;&lt;strong&gt;COPD before age 55&lt;/strong&gt;&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;People with AATD who smoke often develop lung disease &lt;strong&gt;10&amp;ndash;15 years earlier&lt;/strong&gt; than non-smokers.&lt;/span&gt;&lt;/p&gt;
&lt;h3&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Liver Complications&lt;/strong&gt;&lt;/span&gt;&lt;/h3&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Liver disease may include:&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Fibrosis&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Cirrhosis&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Liver failure&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Hepatocellular carcinoma (liver cancer)&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;AATD is a &lt;strong&gt;leading genetic cause of liver disease in children&lt;/strong&gt;.&lt;/span&gt;&lt;/p&gt;
&lt;h3&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Skin and Vascular Complications&lt;/strong&gt;&lt;/span&gt;&lt;/h3&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Panniculitis&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Vasculitis&lt;/span&gt;&lt;br /&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Both are rare but potentially serious.&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;h2&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Diagnosis&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;hr /&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;AATD is diagnosed using:&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Blood tests to measure AAT levels&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Genetic testing (SERPINA1 variants)&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Liver function tests&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Lung function tests (spirometry)&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Imaging such as CT scans&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Testing is recommended for:&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Early-onset COPD&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Unexplained liver disease&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Family members of diagnosed patients&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;h2&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Treatment and Management&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;hr /&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;There is &lt;strong&gt;no cure&lt;/strong&gt;, but treatment focuses on preventing damage and managing symptoms.&lt;/span&gt;&lt;/p&gt;
&lt;h3&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Lung Treatment&lt;/strong&gt;&lt;/span&gt;&lt;/h3&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Smoking cessation (essential)&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Inhalers and bronchodilators&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Pulmonary rehabilitation&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Oxygen therapy&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;&lt;strong&gt;AAT augmentation therapy&lt;/strong&gt; (intravenous replacement in selected patients)&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;h3&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Liver Care&lt;/strong&gt;&lt;/span&gt;&lt;/h3&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Regular monitoring&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Avoiding alcohol&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Managing metabolic risk factors&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Liver transplant in advanced cases&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;h3&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Lifestyle Measures&lt;/strong&gt;&lt;/span&gt;&lt;/h3&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Maintain a healthy weight&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Avoid environmental pollutants&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Stay physically active&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Keep vaccinations up to date&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;h2&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;Prevention&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;hr /&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;AATD cannot be prevented, but disease progression can often be slowed.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Key steps include:&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Never smoking&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Early diagnosis&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Genetic counselling for families&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Avoiding occupational lung irritants&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;h2&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;When to See a Doctor&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;hr /&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Seek medical advice if you or your child has:&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Early or unexplained lung disease&lt;/span&gt;&lt;/li&gt;

&lt;li&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;A family history of AATD&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Early testing allows timely intervention and better long-term outcomes.&lt;/span&gt;&lt;/p&gt;
