So we asked the experts at Google to share the most popular health-related searches of the past year with us.
These top searched health-related questions are based on Google searches in the US from January to November 2015, said Simon Rogers, a data editor for Googles News Lab.
Here are the burning questions you searched for in 2015, along with answers from doctors and Health experts.
The question: Is bronchitis contagious ?
Acute bronchitis is a chest cold that occurs when the bronchial tubes get irritated and inflamed, creating mucus that makes you cough. It may or may not be research results of a bacterial infection, which builds this question a difficult one to answer.
For the most part, bacterial bronchitis and airway inflammation are not contagious per se, said Health editorial advisory board member Dr. David L. Katz ., director of Yale University Prevention Research Center in New Haven, Conn. and founder of True Health Initiative. Often, however, the precipitant for a bout of bronchitis is a viral infection of the upper airwayfrequently called a coldand these, of course, are contagious.
In other terms, patients should think of acute bronchitis as more a symptom of an illness rather than an illness itself.
Generally, bronchitis is a complication of an infection involving the upper respiratory tract, explained Katz. That infection is usually viral, and contagious. The complication of the infectionbronchitisis not contagious, however. The subtlety here is that some viruses can cause bronchial rednes even in the absence of prior vulnerability of bacterial infection, so the no in this instance is a qualified no.
In addition to acute bronchitis, more than 12 million Americans suffer from chronic bronchitis, which is one kind of chronic obstructive pulmonary illnes( COPD ). This condition is typically brought on by cigarette smoking, and is not contagious.

The question: Is pneumonia contagious ?
The answer here is a qualified yes, Katz said, explaining that most cases of pneumoniaan infection that causes the lungs air sacs to fill up with fluidare bacterial. So if you come in contact with person suffering from bacterial pneumonia, its possible for that bacteria to be transmitted to you. He adds that this is particularly true with community acquired pneumonia such as tuberculosis, which is notoriously contagious. There are also strains of pneumonia the hell is viral rather than bacterial, and those are even more contagious.
In general, however, pneumonia is not spread nearly as readily as viral infections of the upper airway, Katz said. It also stops being contagious when coughing stops, usually soon after the initiation of appropriate antibiotics.
The question: How much water should I drink ?
From coconut water to maple water to cactus water, trendy water-like liquors reigned supreme in 2015. When it comes to staying healthy and hydrated, though , nothing beats a plain-old glass of H2O. But how much do you really need each day?
The easiest formula is to take your weight and divide it in half, said Keri Gans, RDN, a New York City-based nutrition consultant and author of The Small Change Diet. The number you get is the amount of water, in ounces, you are able to devour each day.
For example, if you weigh 140 pounds, “youre supposed to” drinking about 70 ounces( or nine beakers) of water a day. However, Gans added that you should always take into account other factors, such as temperature, if youre exert, and if youre pregnant or breastfeeding, in which instance youll likely required more than that.
Another important thing to remember is that water isnt the only way to meet your hydration requires, Gans said. Vegetables, fruit, and unsweetened beverages also count.
The question: How many calories should I eat ?
Unfortunately, theres no one-size-fits-all answer to this question.
Calorie needs are based on age, height, weight, activity level, health status, and if youre pregnant or breastfeeding, said Megan Roosevelt, RD, founder and CEO of Healthy Grocery Girl. For the most accurate calorie intake computations, you should meet with a registered dietician.
Gans agreed: Honestly, I never tell my patients to cut calories, she said. I much favor they focus their attention on creating well-balanced snacks that include nutrient-rich foods and portion control.
However, Gans acknowledged that being aware of how many calories in general youre ingesting can help keep on you on track. She recommends that a 54 female consume between 1,400 and 1,600 calories a day if shes somewhat to reasonably active and upwards of 1,900 calories if shes very active.
But these numbers can still vary even more if were talking about an upper-class athlete or someone who is very sedentary, she said.

Lupus, short for systemic lupus erythematosus, is a chronic autoimmune illnes that affects more than 1.5 million Americans. Depending on its seriousnes, the disease can impact the skin, kidneys, joints, heart, nervous system, and blood cell. Lupus is notoriously difficult to diagnose and is often confused with rheumatoid arthritis.

Before we had blood tests and ultrasounds to help us determine how far along a pregnancy was, we relied on primitive info, said Dr. Joshua U. Klein, assistant clinical professor of OB/ GYN and reproductive science at the Icahn School of Medicine at Mount Sinai Hospital in New York City. Mainly, how big a womans abdomen wasa fairly inaccurate indicatorand when her last period was.
If a woman has a regular period, then the day of her last period is the most reliable( well, semi-reliable, as Klein puts it) method for knowing how far along she is. For women who dont have regular menstrual cycles, though, that kind of dating will be off.
Thankfully, physicians today have more accurate methods for determining how far along a pregnancy is.
The primary instrument we use now is an ultrasound to look at fetus developing, Klein said. In the first six weeks of pregnancy, you can also get a human chorionic gonadotropin( HCG) blood test that measures the level of the pregnancy hormone in your blood.
Either way, knowing exactly when you conceived is important: If youre wrong, your OB could incorrectly calculate your due date, Klein said. And if it appears that youre late for that date nine months later, your doctor may induce the pregnancy prematurely without realise it.
The question: When do you ovulate ?
In women of reproductive age, ovulation happens when an egg is released from the ovaries into the fallopian tubes, where it can be fertilized by sperm. For women with regular menstrual cycle, one of the easiest ways to monitor ovulation is by tracking your period.
If you have a period once a month, youre ovulating once a month, Klein said. And the time of ovulation is usually in the middle of that cycle, approximately two weeks after the day of your last period.
The median menstrual cycle is between 25 and 35 days, Klein said, but if you have longer intervals between periodssay, every two monthsthat means youre merely ovulating once every two months, too. If thats the suit for you, an at-home ovulation exam can assist you pinpoint exactly when ovulation results.
These tests typically have strips that can detect hormonal changes in the urine one to two days before ovulation, Klein said. They can help you get a fairly reliable manage on the one or two days in your cycle that youre going to be ovulating, which is especially helpful if youre trying to get pregnant.
Other than monitoring your period or taking a test, can specific symptoms alert you to ovulation?
Some females know their bodies very well and come to recognize symptoms like abdominal pain, cramps, and breast tenderness around the time that theyre ovulating, Klein said.
However, because those symptoms can so often be indicators of something else, he cautions against relying on them entirely.
