Pulmonary Function Tests or PFTs are a set of tests that are used to determine, measure or observe the functioning of the lungs. The most common pulmonary function tests used are spirometry, gas diffusion, and lung plethysmography. 

Highlights of pulmonary function tests

A spirometry test is used to measure the amount of air inhaled and exhaled. It also measures the amount of time taken to complete a respiration cycle.
A lung plethysmography measures the amount of air in the lungs after the patient has taken a deep breath. It also measures the amount of air that remains in the lungs after the patient has exhaled as much air as possible.
What does a Pulmonary Function Test measure?
Pulmonary function tests would not only check how well the person is breathing but also how effectively the lungs are able to conduct oxygen to the rest of the body. In addition to air flow, these tests would measure the size and volume of the lung and lung diffusion.

These tests can also be used to measure

Total Lung Capacity   the amount of air present in the lungs after breathing in deeply
Forced Vital Capacity   the amount of air that can be exhaled after breathing in deeply
Minute Volume   the amount of air exhaled per minute
Vital Capacity   the total volume of air that can be breathed out after inhaling as much as possible
Tidal Volume   the amount of air inhaled or exhaled when breathing normally
Maximum voluntary ventilation   the amount of air that can be inhaled and exhaled in one minute
Functional Residual Capacity   the amount of air that remains in the lungs when breathing normally
Forced Expiratory Flow   the flow or volume of air during an exhalation
Peak Expiratory Flow Rate   the rate at which a person can exhale
When are Pulmonary Function Tests recommended?
A physician might recommend a patient undergo a PFT as part of a routine physical check-up. This test would be advised if the patient is experiencing any symptoms associated with lung problems or disorders such as asthma, respiratory infections, chronic obstructive pulmonary disease, COPD. A doctor would also use these tests to monitor and check whether a certain treatment prescribed for a lung disease or condition is working effectively.

Pulmonary function tests are safe as they are non-invasive but it is important to follow the instructions of the doctor or technician before, after and during the test. It is important to make your doctor aware of any surgeries, respiratory infections, chest pains or heart attacks that you might have experienced before the test. If you are taking any medications you might need to follow the advice of the doctor as to whether you can take them before the test.

Your doctor would also advice you on how to prepare for the test such as not eating a large meal, avoiding caffeine and wearing loose-fitting clothes. If you have any doubts, concerns or queries discuss them with your doctor.

Pulmonary Function Tests - Why Is It Required?

A heart attack is usually characterised by the rupture of a plaque which can cause the spread of the cholesterol into the blood stream.
Cardiovascular diseases are a major cause of pain, suffering and death around the world, today. Heart attacks are caused by coronary heart disease. This is caused by the narrowing of the coronary artery when substances like cholesterol block it. If not treated and revived on time, a patient suffering from a heart attack can meet a fatal result.

So how can you prevent a heart attack?

1. Cholesterol: We are all affected to some extent by what we eat. It is important to keep a check on your cholesterol, especially if it is on the higher side, so as to prevent a heart attack. Cholesterol is known to directly cause a heart attack, because if applies layer upon layer to the walls of the artery, and chokes them until they cannot handle the pressure any longer. So watch your food intake and bring down the blood lipid or fat levels with proper diet and exercise to alleviate the risk of a heart attack.

2. Assess your Risk Factors: So are you at risk of heart disease and possible heart attack? This will very much depend on your medical history and allied ailments. If you are suffering from high cholesterol or even diabetes, your chances of having clogged arteries and a subsequent heart attack may increase manifold. Also, you may have a family history of heart diseases which can increase the risk of such ailments in your case. So, it is wise to assess your risk factors and take measures like regular checkups, medication where required and even other measures like diet and exercise.

3. Blood Pressure: To prevent a heart attack, you can also keep your blood pressure in check. Constant spikes and dips can lead to a malfunctioning heart which can weaken the heart muscles and lead to a fatal result like a heart attack. Further, high blood pressure can lead to wear and tear of the inner lining of your blood vessels, which makes it that much more difficult for blood flow and circulation. So keep a blood pressure measuring machine or cuff at home, or visit your doctor regularly to keep tabs on your blood pressure.

While these basic measures can help take care of the immediate and most direct causes of heart attacks, you can also avoid passive and active smoking, and indulge in a good diet with plenty of exercise to keep your heart healthy.

Fatty liver is a condition where excess fat is deposited on this organ. Also called as steatosis, this condition happens when more than 5- 10 percent of the weight of the liver is made up of fat.

Fatty liver is a common condition among people. A study from coastal regions of India found ~ 25% of healthy persons had patients had fatty liver on ultrasound.

It can occur at all ages including childhood, highest prevalence is in 40 50 year age group. Prevalence more in patient who are obese and in diabetic patients.

Types of Fatty Liver

1 Alcoholic fatty liver: This condition occurs when there is a heavy consumption of alcohol. Gastroenterologists recommend abstention from alcohol for this condition to subside. If the patient continues to consume alcohol, then liver cirrhosis may develop.

2 Non alcoholic fatty liver (NAFL): One may develop a fatty liver even if one is not an alcoholic. The liver in some cases is unable to process the fat in cells causing them to build-up on the organ.

When more than 10% of the liver is made of fat then this condition is called Non Alcoholic Fatty Liver (NAFL).

Non alcoholic steatohepatitis (NASH): When fatty liver is associated with inflammation in liver patient is said to be having Non alcoholic steatohepatitis. NASH is a more advanced stage of NAFLD, and has a higher risk of progressing to liver cirrhosis or hepatocellular carcinoma (HCC). These condition display symptoms like jaundice, vomiting, nausea, loss of appetite and abdominal pain. Blood test (LFT) shows raised enzymes level. Approx 5-8% of the Indian population has NASH. Consult a doctor if you are experiencing any of these symptoms.

3 Fatty liver during pregnancy: Occurring mainly in the third trimester, the symptoms of this condition are vomiting, nausea, pain the right part of the abdomen and jaundice.

Symptoms

During the early stages (fatty liver) of the disease, patients usually have no symptoms directly related to liver disease. However, people may experience a vague abdominal discomfort. If their liver is inflamed (NASH) then they may display symptoms of poor appetite, weight loss, pain in the abdomen and disorientation.

What causes fatty liver?

The most common cause of fatty liver is alcoholism. When the human liver is unable to metabolize fat fast enough or when there is an excess accumulation of fat on the liver cells then the liver becomes fatty. However, intake of high-fat foods may not result in a fatty liver.

Predisposing factor:

1 Diabetes mellitus

2 Obesity or being overweight

3 Hyperlipidemia or the condition where there are high levels of fat in the blood

4 Genetic reasons

5 Rapid loss of weight

6 Drugs: Aspirin, steroids, tamoxifen, tetracycline etc. cause side effects which also leads to fatty liver

7 Nutritional status (eg, overnutrition, severe malnutrition, total parenteral nutrition [TPN], or starvation diet)

8 Other health problems (eg, Hepatitis C infection, celiac sprue and Wilson disease)

If you are experiencing pain in urination along with a burning sensation, a health condition known as dysuria is indicated. This condition is usually common in women and men alike. However, older men are more prone to face this problem. Pain during urination may occur because of various reasons. The most common causes are as follows:
Infections

Urinary tract infections (UTIs) are a common cause of painful urination. Infections may occur in any part of your urinary tract, such as in the kidneys, bladder, and the ureters. These infections occur due to bacteria, which gets into the urinary tract via the urethra. There are several factors, which increase your chances of being affected by UTI. They include diabetes, an enlarged prostate, old age, pregnancy, and kidney stones. UTI is signified by other symptoms such as fever, bloody urines, flank pain, stronger smelling urine, and an increased urge for urination.
At times, painful urination may also be associated with vaginal infections in women, like yeast infection. Vaginal discharge and foul odor are indicated in the case of vaginal infections.
Painful urination is also caused because of certain sexually transmitted infections (STIs) such as gonorrhea, genital herpes and Chlamydia.
Inflammation and irritation
There are several problems, which can cause inflammation of your urinary tract and genital region. This further results in painful urination. Inflammation and irritations also occur because of other factors such as urinary tract stones, vaginal changes associated with menopause, certain physical activities and the side effects of several medicines, treatment procedures and health supplements.

Consulting a doctor for painful urination
Your doctor will suggest you to undertake certain laboratory tests for the proper diagnosis of the cause of your painful urination. After this, a suitable treatment method is sought and undertaken. Before this, an overall physical examination is also carried out. Your doctor is likely to ask you some important questions regarding your painful irritation, how the condition worsens, and is felt during the onset of urination. It is also likely for your doctor to know about any other symptoms, which you might be experiencing such as fever, flank pain and vaginal discharge. You must tell your doctor about any changes observed in your urine flow, such as difficulty in initiating flow, an increased urge to urinate, and dribbling.

Apart from these, your doctor may also ask whether you experienced any character in urine after painful urination. These may include colour, amount, cloudiness, presence of pus in the urine and so on. 

Pain in Urination - Common Reasons Behind it!

The brain contains numerous nerve cells which help in its normal functioning. Epilepsy or seizures occur when there is a disruption in the activity of the nerve cells in the brain. A neurological disorder of the CNS (Central Nervous System), epilepsy can affect all and sundry, irrespective of their age, sex and ethnicity. However, children and aged people (above 60 years) are more susceptible to the condition. A study suggests approximately 10 million people in India suffer from epilepsy.

Types of Epilepsy
Based on the activity of the brain that causes an epileptic attack, Epilepsy can be of two types - Focal or Generalized
Focal Epilepsy: An epileptic attack triggered by unusual activities restricted to a particular area of the brain.

In some cases, focal epilepsy may result in unconsciousness. A person may also lose awareness and become unresponsive (keeps staring into space), a condition termed as Focal Dyscognitive Seizures. A person with this condition may behave strange, such as walking in circles, chewing or rubbing their hands.
In another type of focal epilepsy known as Focal seizures without loss of consciousness, a person does not lose consciousness. In such cases, there may be sudden and involuntary jerking of the arms or the legs. There may also be dizziness or a tingling sensation.
Generalized Epilepsy: Here, the seizures or epilepsy result from unusual activities throughout the brain. Generalized epilepsy, may, in turn, be of the following subtypes

Tonic seizures: This affects the muscles of the legs, arms, or the back, causing them to stiffen and tighten up.
Atonic seizures: Here, a person may suddenly fall down due to loss of muscle control. The condition is also known as Drop Seizures.
Absence seizures: Mostly affecting children, the affected person may lose awareness (temporary) and behave strangely such as staring into spacing, smacking their lips, or blinking their eyes continuously.
Clonic seizures: They are characterized by sudden and continuous jerking movements of the arms, face, and neck muscles.
Tonic-clonic seizures: Here, a person may suddenly lose consciousness. There are violent shaking and stiffening of the body. Some people may even be seen biting their tongue.
Myoclonic seizures: In this arms, and legs of a person suddenly twitches and jerks.

What triggers an Epilepsy?
Epilepsy may be an outcome of the following factors

Medical conditions such as stroke or even brain tumors may affect the normal activities of the brain, thereby resulting in epilepsy. Diseases such as Viral Encephalitis, AIDS or Meningitis act also act as a trigger, accelerating the chances of epilepsy.
Developmental disorders such as Neurofibromatosis or Autism can also trigger epilepsy.
In some cases, epilepsy may be a genetic predisposition. Thus, a person with a family history of epilepsy may suffer from the condition.
Epilepsy may also be an outcome of a prenatal brain injury due to oxygen deficiency or an infection to the mother.
People with dementia may also suffer from an epileptic attack.

Why do you get PCOS?

Polycystic ovarian syndrome is the condition when a woman's sex hormone levels get imbalanced. This can cause women to have irregular periods and may also have an impact on their fertility. Women suffering from PCOS also tend to grow small cysts in their ovaries which can also lead to severe health problems like diabetes and heart disease, if left untreated.

What causes PCOS?

The exact cause of PCOS is not known. However, the condition may be triggered by hormonal imbalances and genetic factors. Women are more susceptible to developing this condition if their mother or a female family member also has the condition. Excessive production of androgen, which is a male sex hormone, may also lead to this condition. Women suffering from PCOS tend to have high levels of androgen. The formation of eggs and their release during ovulation can be delayed by high levels of androgen. High androgen levels may result from excess insulin present in the blood. Poor lifestyle and irregular eating habits contribute to obesity which intern leads to increased insulin resistance and hence delayed ovulation and irregular cycles leading to infertility.

What are the symptoms of PCOS?


The type of symptom in case of PCOS varies from person to person. Since PCOS is characterized by low levels of sex hormones, this condition may lead to symptoms such as:

- Excessive hair growth on stomach, face, chest, toes and thumbs
- The breast size starts to shrink
- There is a change in voice, making it deeper
- There is excessive loss of hair from your scalp
- Sometimes the face is filled with acne and the skin turns oily
- There are fertility problems like having trouble in ovulating or recurring miscarriages
- Frequent depression or mood swings
- Facing breathings problems while sleeping
- Obesity
