Viral fever is a common condition caused by a viral infection, which affects the body's immune system and causes a rise in body temperature. Here are some common reasons why viral fever occurs:
1. *Viral Infection*: Viral fever is caused by a viral infection, which can be spread through:
- Airborne transmission (inhalation of viral particles)
- Close contact with an infected person
- Contaminated food and water
- Insect vectors (like mosquitoes)
2. *Weakened Immune System*: A weakened immune system makes you more susceptible to viral infections, which can lead to viral fever.
3. *Seasonal Changes*: Viral fever can occur during seasonal changes, especially during monsoon or winter seasons.
4. *Poor Hygiene*: Poor hygiene practices, such as not washing hands regularly, can increase the risk of viral infections.
5. *Viral Load*: Exposure to a high viral load can increase the risk of developing viral fever.
6. *Age and Health Status*: Viral fever can affect anyone, but it's more common in:
- Children under 5 years
- Older adults
- People with chronic illnesses or compromised immune systems
7. *Other Factors*: Other factors that can contribute to viral fever include:
- Stress
- Lack of sleep
- Poor nutrition
- Environmental factors (like pollution)
Some common viruses that can cause viral fever include:
- Influenza (flu)
- Common cold viruses (rhinovirus, coronavirus)
- Respiratory syncytial virus (RSV)
- Rotavirus
- Dengue virus
- Chikungunya virus
Note that this is not an exhaustive list, and many other viruses can cause viral fever. If you're experiencing symptoms, it's essential to consult a healthcare professional for proper diagnosis and treatment.
Class 2
GERD stands for Gastroesophageal Reflux Disease. It's a chronic condition where the stomach acid flows back into the esophagus, causing symptoms and potentially leading to complications.
Here's a detailed explanation:
*What happens normally:*
- The esophagus carries food from the mouth to the stomach.
- The lower esophageal sphincter (LES) is a ring-like muscle that separates the esophagus and stomach.
- The LES relaxes to allow food to enter the stomach and then tightens to prevent stomach acid from flowing back into the esophagus.
*What happens in GERD:*
- The LES becomes weak or relaxes abnormally, allowing stomach acid to flow back into the esophagus.
- The stomach acid irritates the esophageal lining, causing inflammation and damage.
*Symptoms:*
- Heartburn (a burning sensation in the chest)
- Regurgitation (food or acid backing up into the mouth)
- Difficulty swallowing
- Chest pain or tightness
- Coughing or wheezing
- Hoarseness
*Complications:*
- Esophagitis (inflammation of the esophagus)
- Stricture (narrowing of the esophagus)
- Barrett's esophagus (pre-cancerous changes in the esophagus)
- Respiratory problems (e.g., asthma, pneumonia)
*Treatment options:*
- Lifestyle changes (e.g., weight loss, avoiding trigger foods, elevating the head of the bed)
- Medications (e.g., antacids, acid reducers, proton pump inhibitors)
- Surgery (e.g., fundoplication, LINX procedure)
It's important to consult a healthcare professional for proper diagnosis and treatment if you're experiencing symptoms of GERD.

- Structural disorders (e.g., peptic ulcer disease, diverticulitis)
- Neoplastic disorders (e.g., colon cancer, GISTs)
- Infections (e.g., hepatitis, gastroenteritis)
- Motility disorders (e.g., achalasia, scleroderma)
It's important to note that this is not an exhaustive list, and there are many other diseases and conditions that can affect the digestive system.
