In recent years, respiratory illnesses have been on the rise, especially those caused by viruses. Such diseases can affect the entire respiratory system, from the sinuses to the lungs. Although some symptoms associated with these conditions tend to resolve on their own, others may require medical intervention. That is why recognizing the symptoms early on and getting timely treatment may help in managing the condition. So, here are 14 early signs of respiratory infections: 1. Fever A fever is generally one of the first signs of a respiratory infection. It is the result of the immune response to viruses, as many such pathogens are sensitive to temperature changes in the body. Upon noticing this sign, one must consistently monitor their body temperature, as a persistent fever may be an indication of a severe respiratory virus. Here, seeking medical attention is important if the body temperature crosses 100.4°F (38°C). A temperature as high as 101 to 102°F (about 38.3 to 38.9°C) is common for those infected by influenza. However, fevers over 103°F require immediate treatment. At times, this symptom may be accompanied by night or cold sweats. As the internal temperature increases, the body may induce sweating to prevent overheating and help one cool down.

Heartburn is a prevalent condition that affects millions of people worldwide. The burning feeling in the chest caused by the onset of heartburn can cause discomfort. The condition can be temporary or chronic if left unmanaged. It occurs when stomach acid flows back into the esophagus, causing irritation and discomfort. Recognizing the early symptoms of heartburn is crucial for timely intervention and effective management. Let’s look at the subtle indicators of heartburn. What is heartburn? Heartburn, known as acid indigestion or acid reflux, is a condition where the stomach acid rushes back up into the esophagus (a tube carrying food from the mouth to the stomach, and it is not designed to handle the corrosive effects of stomach acid). The acid reflux generally leads to a range of uncomfortable symptoms. The primary reason behind heartburn is a dysfunctional lower esophageal sphincter (LES). It is a muscle ring situated at the bottom of the esophagus that normally acts as a one-way valve, allowing foods and liquids to enter the stomach while preventing stomach contents from flowing back up into the esophagus. When the LES weakens or relaxes inappropriately, stomach acid can escape into the esophagus, leading to heartburn. Early symptoms of heartburn Burning sensation in the chest This is a common sign of the condition, often erupting from behind the breastbone.

Chronic obstructive pulmonary disease, also known as COPD, is a term used by healthcare professionals to refer to a group of lung conditions, including emphysema and chronic bronchitis. Over time, COPD can cause patients to experience breathing difficulties. While one cannot reverse the lung damage, patients can make certain lifestyle changes to manage the condition and its associated symptoms. Continue reading to learn more about the symptoms and treatment alternatives of COPD. Symptoms of COPD Generally, the symptoms of COPD do not make an appearance until the condition has progressed significantly, leading to extensive lung damage. Furthermore, the continuation of certain poor habits can make the condition worse over time. Here are some of the signs of COPD mentioned below. Tightness in the chest One of the most common symptoms of COPD, chest tightness, can manifest in different ways across patients. While for some it can be noticed in the form of breathing difficulties, for others it can feel like a weight on the chest. This can increase the risk of pain while breathing. Some of the main causes of the issue are damage to lung’s air sacs, airway obstruction, respiratory infections, and bronchospasms. Wheezing This symptom of COPD is often accompanied by tightness in the chest.
