Cirrhosis -

Moderating alcohol intake can help prevent liver damage and cirrhosis. You can also prevent nonalcoholic fatty liver disease by enjoying a nutritious diet rich in fruits and vegetables.

9. Tuberculosis -

Tuberculosis (TB) is a lung condition caused by bacteria called Mycobacterium tuberculosis. It's a treatable airborne bacterium, although some strains are resistant to conventional treatments.

8. Dehydration due to diarrheal diseases -

If your diarrhea lasts more than a few days, your body loses too much water and salt. This causes dehydration, which can be fatal in severe cases.

Dehydration due to diarrheal diseases -

Diarrhea is usually caused by an intestinal virus or bacteria transmitted through contaminated water or food. It's particularly widespread in areas with poor sanitary conditions. The best method of prevention is practicing good hygiene.

6. Diabetes mellitus -

Diabetes affects the production or use of insulin. In type 1 diabetes, the pancreas is unable to produce insulin. This type of diabetes is believed to be caused by an autoimmune reaction. In type 2 diabetes, the pancreas doesn't produce enough insulin, or insulin can't be used effectively. This type can be caused by a number of factors, including poor diet and lack of physical activity.

Diabetes mellitus -

Over time, uncontrolled diabetes can cause damage to the nerves and blood vessels. This can lead to complications such as impaired wound healing, kidney failure, and blindness.

Respiratory cancers -

The main causes are smoking, secondhand smoke, and environmental toxins. However, household pollutants, such as fuels and mold, also contribute.

Respiratory cancers -

Aside from avoiding fumes and tobacco products, there isn't any other known way to prevent lung cancers. However, routine lung scans and early detection can result in more effective treatment and an improved outlook.

4. Chronic obstructive pulmonary disease -

Chronic obstructive pulmonary disease (COPD) is a long-term, progressive lung disease that makes breathing difficult. Chronic bronchitis and emphysema are types of COPD.

Chronic obstructive pulmonary disease -

Risk factors for COPD include smoking or secondhand smoke, chemical fumes, family history, or respiratory infections as a child.

Chronic obstructive pulmonary disease -

There's no cure for COPD, but its progression can be slowed with medication. Also, the best ways to prevent COPD are to stop smoking and avoid secondhand smoke and other lung irritants.

3. Lower respiratory infections -

A lower respiratory infection is an infection in your airways and lungs. It can be caused by influenza, pneumonia, bronchitis, or tuberculosis (TB).

Lower respiratory infections -

Coughing is the main symptom of a lower respiratory infection. It may produce blood sputum. You may also experience a fever, sweating, chills, breathlessness, wheezing, and a tight feeling in your chest.

Stroke -

During a stroke, you feel sudden numbness and confusion or have trouble walking and seeing. If left untreated, a stroke can cause long-term disability. But people who receive treatment within three hours of having a stroke are less likely to have disabilities.

Stroke -

Smoking, family history with stroke, and high blood pressure are common risk factors. However, these factors can be lowered with preventive care, medications, and lifestyle changes.

1. Ischemic heart disease, or coronary artery disease -

The deadliest disease in the world is coronary artery disease (CAD). Also known as ischemic heart disease, CAD occurs when the blood vessels that supply blood to the heart become narrowed. Untreated CAD can lead to chest pain, heart failure, and arrhythmias.

Ischemic heart disease, or coronary artery disease -

Risk factors of CAD include high blood pressure, high cholesterol, family history with CAD, diabetes, smoking, and being overweight.

Ischemic heart disease, or coronary artery disease -

CAD is preventable with medications and by taking steps to improve heart health, including regular exercise, maintaining a moderate weight, and eating a balanced diet.
