What is hepatitis B?

A liver infection known as hepatitis B is brought on by the hepatitis B virus (HBV). One of the five varieties of viral hepatitis is HBV. Hepatitis A, C, D, and E make up the other four. Each one is a distinct kind of virus. The most likely types to develop chronic or long-lasting are types B and C.

Around 296 million individuals worldwide are thought to be infected with hepatitis B, according to the World Health Organization. In 2019, around 1.5 million new cases of chronic hepatitis B were reported.

Acute or chronic HBV infection are both possible. Adults with acute hepatitis B experience sudden onset of symptoms. Rarely do newborns who receive hepatitis B at birth simply experience acute symptoms. The majority of baby hepatitis B infections progress to chronic disease.

What are the types of hepatitis B?

Hepatitis B infections come in two flavours: acute and chronic.

Acute

When you contract hepatitis B for the first time, an acute infection occurs. Many people can get it out of their bodies and feel better. In fact, roughly 4 out of 5 sick adults fit this description.

Chronic

You have chronic hepatitis B if you are unable to get rid of the virus within six months or longer. (Chronic denotes continual.) The dangerous, sometimes fatal diseases of liver cancer and cirrhosis of the liver are caused by chronic hepatitis B, which also causes inflammation. Treatment can halt the progression of the condition, lower the risk of developing liver cancer, and improve survival rates.

What are the symptoms of hepatitis B?

Acute hepatitis B symptoms can not show up for several months. However, typical signs include:

An early evaluation is required for any hepatitis B symptoms. Acute hepatitis B symptoms worsen in those over 60. If you believe you may have been exposed to hepatitis B, tell your doctor right once. It’s possible that you can stop an infection.

How common is hepatitis B?

According to the WHO, around 296 million people around the globe live with chronic HBV. Around 1.5 million new infections occur every year.

According to the Centers for Disease Control and Prevention (CDC), chronic hepatitis B affects approximately 1.2 million people in the United States.

But HBV often goes undetected. In fact, the WHO estimates that only about 10.5% of people living with hepatitis B were aware of their condition as of 2019.

Causes and risk factors for hepatitis B

A viral infection called hepatitis B can be spread by blood or other body fluids like vaginal or sperm.

Hepatitis B can be spread, among other things, by:

  • having intercourse without using a condom or other barrier techniques with a person who has HBV
  • sharing blood-contaminated razors, nail clippers, or toothbrushes
  • getting a tattoo or a body piercing with unsterilized equipment
  • sharing needles, syringes, or other supplies while injecting narcotics
  • from a parent giving birth to a newborn child

Although the virus may be found in the saliva, hepatitis B is not transmitted through:

  • kissing
  • sneezing
  • coughing
  • sharing cutlery

HBV infection is more likely to occur in some groups than others. These comprise of:

  • medical professionals
  • users of injectable medications
  • infants conceived by HBV-positive parents
  • HBV-positive individuals’ sexual partners
  • people with renal disease who are on dialysis

Complications of hepatitis B

Chronic hepatitis B complications include:

  • the hepatitis D virus
  • hepatic scarring (cirrhosis)
  • liver damage
  • liver tumour
  • death

Only those who have hepatitis B can get hepatitis D. Although hepatitis D is rare in the US, it can also cause chronic liver disease.

Crohn’s disease: Top bad thing to your digestive system.

Inflammatory bowel illness includes Crohn’s disease (IBD). It results in the tissues in your digestive tract swelling (inflammation), which can cause abdominal pain, severe diarrhoea, exhaustion, weight loss, and malnutrition.

People with Crohn’s disease may experience inflammation in many parts of their gastrointestinal tract, most frequently the small intestine. This inflammation frequently penetrates the innermost layers of the bowel. The symptoms of Crohn’s disease can occasionally be life-threatening and can be both unpleasant and incapacitating.

Although there is no proven treatment for Crohn’s disease, medicines can significantly lessen its signs and symptoms and even result in long-term remission and inflammatory healing. With medication, many Crohn’s disease sufferers can lead productive lives.

Types of Crohn’s disease

Different parts of the digestive system may be impacted by Crohn’s disease. The following list includes many forms of Crohn’s disease:

  • Ileocolitis: Inflammation affects the small intestine and a portion of the colon’s big intestine. Crohn’s disease most frequently manifests as ileocolitis.
  • Ileitis: The small intestine swells and becomes inflamed (ileum).
    Gastroduodenal: The stomach and the top of the small intestine are both affected by inflammation and irritation (the duodenum).
  • Jejunoileitis: Patchy inflammation appears in the top portion of the small intestine (called the jejunum).

Who might get Crohn’s disease?

The cause of Crohn’s disease is unknown. Your likelihood of getting the illness may be impacted by a number of variables, including:

  • Autoimmune disease: Your immune system may attack healthy cells as a result of digestive tract bacteria.
  • Genes: Inflammatory bowel disease(IBD) is a genetic condition that frequently runs in families. You may be more likely to get Crohn’s disease if one of your parents, siblings, or other family members does. People who have a number of certain gene mutations (changes) may be predisposed to Crohn’s disease.
  • Smoking: Smoking cigarettes could more than double your risk of developing Crohn’s disease.

These kinds of infections can become worse due to immune system issues caused by Crohn’s disease and associated therapies.

Yeast infections, which can harm the lungs and the digestive system, are frequent in people with Crohn’s disease. To avoid further difficulties, it’s crucial that these infections are correctly recognised and treated with antifungal drugs.

Crohn’s symptoms

Crohn’s disease signs and symptoms frequently appear gradually. Over time, some symptoms could possibly deteriorate more. Although it’s possible, it’s uncommon for symptoms to appear out of the blue. The following are some of the first signs of Crohn’s disease:

  • diarrhoea
  • stomach pains
  • stool with blood
  • fever
  • fatigue
  • reduced appetite
  • slim down
  • after having a bowel movement, you still feel like your bowels aren’t empty.
  • feeling the desire to go to the bathroom a lot

These symptoms can occasionally be confused with those of a different illness, such as food poisoning, an upset stomach, or an allergy. If any of these symptoms continue, you ought to visit your physician.

As the illness worsens, the symptoms could get worse. More problematic signs could be:

  • a discomfort and drainage-causing perianal fistula close to your anus
  • Anywhere from the mouth to the anus, ulcers may develop
  • swelling of the skin and joints
  • breathing difficulties or a reduced capacity for exercise as a result of anaemia

Early identification and detection can help you prevent serious problems and start treatment sooner.

Outlook

More efficient therapies and perhaps even a cure for Crohn’s disease are still being sought for by researchers. However, symptoms can be well controlled, and remission is conceivable.

Your doctor can help you locate the proper prescription drugs, complementary therapies, and lifestyle changes that can be beneficial.

Consult your doctor if you experience gastrointestinal symptoms to identify the source and any relevant treatments.

What are the symptoms and causes of Tuberculosis?

What are the symptoms and causes of Tuberculosis?

A potentially dangerous infectious disease that mostly affects the lungs is tuberculosis (TB). People can contract tuberculosis from one another by coughing or sneezing small droplets of bacteria into the air.

Infections of tuberculosis, once uncommon in wealthy nations, started rising in 1985, in part due to the appearance of HIV, the virus that causes AIDS. HIV impairs the immune system, making it incapable of warding off TB pathogens. In the United States, tuberculosis started to decline once more in 1993 as a result of more effective control initiatives. But it still raises questions.

The majority of medications used to treat tuberculosis don’t work on many forms of the disease. For months, those with active tuberculosis must take a variety of drugs to treat the infection and prevent antibiotic resistance.

Different kinds of tuberculosis

You may also hear about several forms of TB, such as the most prevalent, pulmonary (lung) tuberculosis, in addition to active or inactive TB. But in addition to your lungs, the bacterium can also harm other parts of your body, leading to extrapulmonary tuberculosis (or TB outside of the lung). Additionally, systemic miliary TB, which can affect the entire body and result in:

  • Meningitis is a brain inflammation.
  • High quantities of white blood cells in your urine are referred to as sterile pyuria.
  • Spinal tuberculosis, often known as Pott’s disease or TB spondylitis.
  • an adrenal gland disorder called Addison’s disease.
  • The liver infection hepatitis.
  • Neck lymphadenitis, often known as scrofula or TB lymphadenitis.

Who is most at risk?

The majority of persons with tuberculosis are in their prime working years. All age groups, though, are in danger. In low- and middle-income nations, there are more than 80% of cases and fatalities.

Active TB is 18 times more likely to develop in HIV-positive people. Additionally, people with other immune-system compromising illnesses are more likely to have active TB. Undernourished individuals are three times as vulnerable. In 2021, there were 2.2 million new TB cases worldwide that could be linked to malnutrition.

Smoking and problematic alcohol use both raise the risk of TB. The causes of 0.74 million new cases of tuberculosis (TB) worldwide in 2021 were related to alcohol use disorders, while 0.63 million were related to smoking.

Symptoms of tuberculosis?

The majority of persons harbouring TB germs in their systems don’t develop TB disease. They actually still have a latent TB infection. If you have latent tuberculosis, you:

  • had no symptoms
  • cannot transmit TB to others
  • In the future, if your immune system deteriorates due to another factor, you could become ill with active TB illness.
  • Must take medication to avoid contracting active TB disease in the future

The TB bacteria are active if you have TB disease, which means they are growing (multiplying) inside of your body and making you ill. You can distribute the TB germs to other individuals if the disease is developing in your lungs or throat. TB disease can strike weeks to years after you’ve contracted the infection.

Your TB symptoms will depend on where the disease is spreading in your body.

Typical general signs include:

  • the flu with a fever
  • sweats at night (heavy sweating during sleep)
  • shedding pounds without trying
  • reduced appetite
  • weakness or exhaustion

Your lungs’ TB illness symptoms could include the following:

  • Cough that persists for more than three weeks
  • coughing up sputum or blood (a thick mucus from the lungs)
  • chest pain

What causes tuberculosis?

TB is brought on by a bacteria known as Mycobacterium tuberculosis. There are numerous TB strains, some of which have developed drug resistance.

Airborne droplets that are infected with the TB bacteria can spread the disease. Anyone around can breathe in these droplets once they are in the air. TB patients can spread the germs by:

  • sneezing
  • coughing
  • speaking
  • singing

Even if they have contracted the germs, people with healthy immune systems may not show signs of TB. Latent or dormant TB infection is what this is. Latent TB affects about one-fourth of all people on the planet.

Although latent TB is not contagious, it can eventually develop into an active illness. You can get sick from active TB disease and spread it to other people as well.
