“It’s NOT normal to snore. Sleep apnea makes just about every other health condition worse because you aren’t sleeping, and your body can’t heal and recover. Get it checked out ASAP.”

As a Senior Staff Writer at BuzzFeed, I cover real-life stories that explore relationships, lifestyle (including travel and beauty), and the internet's most fascinating trends.

"Ditto: if you’re tired all the time and fall asleep every time you sit down."

"Sleep apnea. I've seen patients come in with pretty bad heart failure after never using their CPAP machine at night. People have no idea how much strain being unable to breathe at night affects their hearts. Use your CPAP machine! It may be ugly, but it will keep your heart strong so you can live out the many years you have left."

"If it isn't getting better or you need an over-the-counter medication frequently to control reflux, it is worth seeing your doctor!"

"Other symptoms you might have with a CSF leak are a headache that worsens when you stand up, nausea, vomiting, or neck stiffness. If you have these symptoms, go to the doctor as soon as possible because your brain will be vulnerable to infection."

"I was tasked with starting a tube into his stomach to suction off the fecal matter, but he was just vomiting so much we were worried he might aspirate poo into his lungs — which is exactly what happened when he was taken to the Operating Room to work on his bowel obstruction. At some point in the OR, during or after the intubation, liquid poop that had festered in his GI system entered his lungs. They brought him back mid-code, and he died soon after. He hadn't had a true bowel movement in over two weeks. He knew, family knew. But he tried to tough it out and kept eating full meals without pooing. He was 45 years old, now departed."

"There are many, many different kinds of acute leukemias, some of which can be more mild and 'easily' treatable, but there are some that are incredibly progressive, and the time from initial diagnosis to death is a matter of days; not to get into it scientifically, but the degree of severity has to do with what kind of blood cell is the cancerous one. It's always better to be safe than sorry, especially since just one simple and routine lab test can determine whether or not this is an avenue the pathologists need to go down for a diagnosis."

"Lifestyle changes, like diet and exercise, are so important, but I understand it's tough to stick with them sometimes. But taking a pill or two is easy, and most of these drugs are very cheap. Just take your meds!!!!!!"

"Go to the ER right away if you feel this because it usually does mean something very bad will happen if you don't."

"And have blood work completed at the same frequency. This woman could have had a chance if she kept up regular medical visits."

"If you are losing weight and can't figure out why, please see your doctor and get some testing done. It could save your life."

"I've seen otherwise smart and competent patients severely and negatively impact their health and quality of life by not being active."

"P.S.: Urgent Care is NOT an ER. Many Urgent Care offices have long waits because people come with EMERGENCY problems since we are closest, or 'I don't want to WAIT there!!!'"

"Common sense should be used but then again you can look around these days and know that common sense is not common!"

"See your dentist and hygienist regularly, at least every six months. REMEMBER: HEALTHY GUMS DON’T BLEED!"

"Mental health nowadays is seemingly almost glorified. A ton of people are blaming things on, 'Oh, it's just my OCD, ADHD, dyslexia, etc.' (undiagnosed as well) — when these sudden changes can be huge telltale signs of actual diseases. I saw someone come into our neuro department after experiencing some fasciculations that we assumed were benign. But she explained how they acted with her 'anxiety and OCD,' which she had undiagnosed. She had late-stage MS."

"I'm always impressed at the people who think they're having a stroke, are in fact having a stroke, and still wait to see if they feel better the next day before going to the hospital."

"When asked why they haven't refilled their Metformin or Norvasc since January, many patients will shrug their shoulders. They either changed insurance, lost their insurance, or say they just felt fine and thought they could go without it for a while."
