How serious is Lyme Disease ?

Lyme disease , or borreliosis , is a potentially life - threatening condition that is transmitted to humans by black legged ticks.

The tick infects the person with the bacterium Borrelia burgdorferi (B.burgdorferi). 


At first , a rash may appear. This can disappear without treatment , but in time , the person may develop problems with the joints , the heart , and the nervous system.

Lyme disease is the most common tick - borne infectious disease in the United states (U.S) . The ticks pick up the bacteria when they bite a mice or deer that are carrying it.

It was first reported in 1977 in a town called old Lyme , CT .


Symptoms : 

Initial signs and symptoms of Lyme disease are usually very mild. Some people may notice any symptoms , or they may think they have flu.

After the initial phase, further symptoms develop.

Symptoms can disappear , but the disease can affect the body in other ways, years later.

Stage 1 : Early Lyme Disease

Erythema migrans (EM) is a rash that often appears in the early stage of Lyme disease , from 3 to 30 days after infection , or 7 days on average.

The rash :
  • typically begins as a small red area that expands over several days, to reach a diameter of 12 inches or 30 centimeters.
  • may lose its color in the center , giving a bull's eye appearance.
  • usually starts at the site of the tick bite but can appear elsewhere as the bacteria spread.
  • is not painful or itchy but may feel warm to the touch. 

Stage 2 : Early disseminated Lyme Disease

The rash will disappear after 4 weeks , even without tretament , but other symptoms can emerge days to months after being bitten.

These include :
  • meningitis, or inflammation of the brain and spinal cord
  • additional rashes
  • fever and chills
  • swollen lymph nodes
  • fatigue
  • pain in tendons, muscles, joints and bones
  • heart palpitations
  • shortness of breath
  • nerve pain
  • numbness in hands and feet
These symptoms may go away without treatment within a few weeks or months, but in time the person may experience further complications.

Stage 3 : Late disseminated Lyme Disease   

It is also known as late Lyme disease . Symptoms can emerge weeks , months, and even years after initial infection if a patient has not received treatment , or if antibiotic treatment has not been fully effective.
It can involve problems with the nervous system and the heart.

The person may have :
  • difficulty concentrating
  • sleep and vision problems
  • memory loss
  • numbness, pain and tingling
  • irregular heart beat
  • joint pain
  • paralysis of the face muscle.
Transmission : 
The Lyme disease causing bacterium enters humans through the bite of an infected black legged tick.
The adult tick or the young nymph bores a tiny hole in the skin and inserts its mouth part into the opening , attaching itself to the host.
Tick tends to attach to hard to see areas of the human body , such as scalp, armpits and groin.

Generally , the tick must remain attached for at least 36 to 48 hours before transmitting the bacterium into a human.

Lyme disease cannot spread between human by touching, kissing or sexual contact.
Dogs and cats can get Lyme disease , but they cannot infect humans. Lyme disease cannot be passed on through the air , food and water.

Treatment :
During the early stage of Lyme disease, treatment with antibiotic medication generally results in a rapid and complete recovery.
In the later stages, especially if the person has arthritis and neurological conditions, intravenous antibiotics, or antibiotic injections, will be necessary.

Prevention :
  • be alert for symptoms
  • be aware of the risk
  • use repellent of the skin, clothing
  • treat pets with anti tick treatment
  • shower after coming from outside
  • ask for pest control regularly

Does Vaping Causes Cancer ?

 What is Vaping? E - cigarettes, sometimes called vapes, run on batteries and heat up nicotine, flavorings, and other chemicals. They turn them into a vapor you can breath in. Many chemicals that causes cancers are in the this vapor, that includes formaldehyde, heavy metals, and particles that can get stuck in the deepest parts of your lungs. Electronic cigarettes or e-cigarettes , put nicotine into your lungs and bloodstream, and they do it without the smoke and tar of a regular cigarette, but other harmful things can get into your body when you vape. That especially true if you use flavored cigarettes. Some chemicals in e- cigarettes can irritate the airways in your lungs. This can cause problems. Studies have found that flavorings like cinnamon can cause inflammation of lung cells. How do e-cigarettes work ? E- cigarettes heat a liquid called e- liquid or e-juice to turn it into aerosol(vapor). E-cigarettes users inhale this into their lungs. How vaping can affect your Lungs Ove...

Are We Brainwashed During Sleep?

 In a new study, researchers suggest that tonight while you sleep, something amazing will happen within your brain. Your neurons will go quiet. A few seconds later , blood flow out of your head . Then, a watery liquid called cerebrospinal fluid (CSF) will flow in, washing through your brain in rhythmic, pulsing waves. The study is the first to illustrate that the brain's CSF pulses during sleep,and that these motions are closely tied with brain wave activity and blood flow. The research was conducted by a team from Boston University. Earlier studies have suggested that CSF flow and slow-wave activity both help flush toxic,memory impairing proteins from the brain. As people age, their brains often generate fewer slow waves. In turn, this could affect the blood flow in the brain and reduce the pulsing of CSF during sleep., leading to buildup of toxic proteins and a decline in memory abilities. Although researchers have tended  to evaluate these processes separately, it now appea...

Sweet Poison : Why Sugar is Ruining your Health

Did you know some of the main ingredients in most of your pantry foods and refrigerated sauces contain sugar? Usually sugar is added to foods in the forms of simple sugars such as glucose, fructose or sucrose, but often manufacturer will disguise the amount of sugar by listing it under several different names. Some of them are : Barely malt Brown rice syrup Corn syrup Dextrin Dextrose Ethyl maltol Have you ever wondered why processed sugar consumption is bad for you ? Quitting sugar has a lot of benefits. Let's face it , very few people go for a day without consuming sugar. However, not all of it is bad. For instance, sugar from milk products(lactose) is healthy. In addition to that, sugar from some fruit products (fructose) is also healthy. In other words it can only be healthy when it is consumed in its natural form and moderate amounts. Unfortunately, most sugar that we consume is unhealthy, artificial, and slowly killing us. Although it helps to make your food sweet , the negat...
