Top Causes for Shortness of Breath

Shortness of breath, also known as dyspnea, occurs when one feels they cannot get enough air into their lungs to breathe normally. It may occur when walking, climbing stairs, engaging in other physical activities, or doing nothing. It may develop suddenly or over some time. Sudden or unexpected breathlessness generally occurs due to health conditions and requires immediate attention from a doctor, especially when accompanied by chest pain, fainting, or nausea.

Top causes for shortness of breath

Carbon monoxide poisoning
When one breathes in carbon monoxide, the chemical replaces the oxygen content in the body. This results in the vital organs being starved of oxygen, causing symptoms like shortness of breath, rapid breathing, chest pain, confusion, convulsions, dizziness, drowsiness, and fatigue. Young children, senior adults, people with lung or heart disease, and people at higher altitudes are at a higher risk of suffering from carbon monoxide poisoning.

Heart conditions
When the heart does not pump enough oxygen-rich blood through the body, the body responds by breathing faster to ensure an uninterrupted supply of oxygen to the vital organs, causing a sensation of shortness of breath. Heart conditions like angina, heart attacks, heart failure, atrial fibrillation, and others are common causes behind the interruption of circulation of blood around the body, causing shortness of breath or breathlessness.

25 signs and symptoms of pneumonia to know of

Pneumonia is a common respiratory infection that can affect people of all ages, causing various symptoms that vary in severity. At the same time, many are familiar with the hallmark signs such as fever and cough, shortness of breath, chest pain, and numerous other indicators that can point to pneumonia. This comprehensive article thoroughly explores pneumonia’s signs and symptoms, helping individuals recognize the condition early and seek appropriate medical care. Fever Fever is one of the most prevalent symptoms of pneumonia. It typically presents with a high body temperature, often exceeding 100.4°F (38°C). Fever is the body’s natural response to infection and signifies that the immune system is actively fighting the pneumonia-causing pathogens. Cough A persistent cough is another hallmark symptom. It can produce different types of mucus, including yellow, green, or bloody. The cough may be accompanied by chest pain or discomfort ranging from mild to severe. Shortness of breath Many individuals with pneumonia experience shortness of breath, particularly when engaging in physical activities. This symptom occurs due to the inflammation and infection within the lungs, making it challenging for the respiratory system to function optimally. Chest pain Chest pain is often described as a sharp or stabbing sensation typically felt on the side of the affected lung.

13 foods that worsen breathing difficulties

The lungs are one of the most vital organs in the human body. Thus, they must remain in good shape to live a healthy life. However, many foods can unknowingly cause them harm and worsen breathing difficulties, whereas adding the proper nutrients to the food regime can help one breathe easier and minimize symptoms of conditions like asthma and COPD. Here are some of the worst foods for lung health that may worsen breathing difficulties: Processed meat Processed meats such as bacon, ham, hot dogs, sausages, and other lunch meats are often treated with additives and preservatives to add flavor and extend their shelf life. This can harm lung health and function. According to certain research, processed meats have been linked with an increased risk of chronic obstructive pulmonary disease (COPD), which may cause breathing difficulties. Additionally, processed meats also contain sodium nitrite, a known carcinogen that can increase one’s susceptibility to lung cancer. Vegetable oil Vegetable oils are used in most households to cook food. However, certain oils, such as canola oil, soybean oil, corn oil, sunflower oil, grapeseed oil, and safflower oil, can be dangerous for the lungs. This is because they contain unhealthy fats that can lead to heart disease, increased inflammation, and excessive mucus production, which may impact one’s breathing.

Hidden Signs of Thyroid Cancer

Thyroid cancer starts in the thyroid gland, a small organ located in the neck. It can occur in people of all ages but is more common in women and people over 60. The exact cause of thyroid cancer is unknown, but factors such as exposure to radiation or family history may increase the risk. Treatment options include surgery, radiation therapy, and hormone therapy. Awareness of thyroid cancer’s signs can help with early detection and treatment. Trouble swallowing The most characteristic sign of thyroid cancer is a lump or swelling in the neck. In some patients, this can cause trouble with swallowing. Dysphagia, another name for this problem, is when a person has a hard time getting food or liquids from their mouth to their stomach. The gland’s tumor may enlarge to the point where it presses against the esophagus or windpipe, making it difficult to gulp down and causing a sense of fullness in the throat. Benign thyroid nodules are one condition that can make swallowing difficult. It should be noted that such problems are uncommon because the nodule must be sufficiently large and situated in a way to obstruct normal food flow. The Centre for Disease Control and Prevention states that difficulty swallowing without any other accompanying illnesses or conditions might occasionally be an indication of thyroid or throat cancer.
