We’ve gotten a lot of requests to write a post about nosebleeds so I thought I would cover some of the basics. As we’re going along remember this: While scary and annoying, most nosebleeds don't point toward anything concerning.

What causes nosebleeds?

If you are like me, nosebleeds will never be the same after Eleven and Stranger Things. But don't get things upside down on the actual cause of your child's bloody nose.

The nose has tons of blood vessels that go to it...and the tissue inside the nose is very fragile and can easily crack and bleed.

Anything that causes the tissue to be dry can lead to increased risk for nosebleeds, especially dry and very cool or warm air (winter and summer). Conditions which lead to nasal inflammation (especially nasal allergies) can also be a factor.

Ultimately, the most common trigger to a bleeding is nose picking but extreme heat, activity and stress can also be a factor. Yes, your kids pick their nose. Every kid picks their nose. I promise. Other common triggers are blowing and suctioning.

There are a few more unusual causes of nosebleeds that should be considered if the nose bleeds are consistent over time:

1. Structural problems - An abnormal bump or growth can be more prone to injury.
2. Bleeding problems - Children who have problems with blood clotting can be more prone nosebleeds.
3. Object stuck in the nose - Sometimes kids put stuff in their nose. Symptoms are usually one sided bleeding and a foul smell from the nostril.

How do you stop a nosebleed?

Pinch it. Pack it. Head up. Head down. What is the right thing to do?

There's no reason to tilt the head back or to lie down. This only increases the amount of blood that is traveling down the back of the throat and can lead to coughing or vomiting blood later.

• Have your child sit or stand and slightly lean forward and breathe through their mouth.
• Firmly pinch your child nose in the soft part just below the bony ridge.
• Hold pressure at that location for 10 minutes. Don't check. Seriously, if you're reading this now, don't check.
• If the bleeding does not stop, repeat again for 10 minutes.
• If the bleeding does not stop, continue holding pressure but get ready to head in to be checked out by a doctor.

When should you be concerned about nosebleeds?

It can be difficult to know what is normal and what is concerning with nosebleeds.

Here are some indications that you should probably see your doctor:

1. An individual nosebleed that doesn't resolve after  two attempts to control bleeding for 10 minutes.
2. Nosebleeds are happening more than 2-3 times per week or are significantly increasing in frequency.
3. There are other associated symptoms such as bruising or easy bleeding, fever, weight loss or rash.
4. Nosebleeds are consistently occurring from one nostril.
5. You should always seek care sooner if your child has an underlying medical condition.

How can I prevent nosebleeds?

In children who have frequent nosebleeds, there are some steps that you can take to help prevent them.

• Keep your child's nails clipped.
• Run the humidifier in the room with your child overnight.
• Apply nasal saline spray to the nose a few times per day. If this doesn't seem to be enough, saline gels or vaseline may also be an option but talk with your doctor.
• Seek medical care for underlying conditions, especially allergies and be consistent with your allergy regimen.

As I was writing this, I received a bunch of emails I plan to answer in a followup, but for now I'm going back to watching Stranger Things.

But, every now and then, something really interesting grabs my attention as something that you might find interesting, even if it’s highly unlikely you’ll ever see it. This is one of those posts.

Children can cry bloody tears. It’s very rare. It’s usually not caused by anything concerning. But, imagine if your child walked up to you with blood streaming down his or her face.

What are the possible causes?

1. Trauma

I would hope that if your child got poked in the corner of the eye and was crying bloody tears, you would be able to quickly deduce the cause but here it is.

2. Infection

Sometimes infections (like pink eye) can cause enough inflammation such that bleeding can occur. The tissue around the eye is pretty fragile and when it is inflamed, small cracks can cause it to bleed.

3. Just Because

Bloody tears seem to sometimes happen just because. Even after investigation into possible causes, no diagnosis is made. These cases tend to resolve over a few months.

4. Conditions that Cause Easy Bleeding

There are a few conditions that can cause children to bleed more easily. Some children are born with them and some develop them over time. If a child has easy bleeding or excessive bruising, this could be the cause.

5. Bloody Noses

Children with bloody noses can also shed bloody tears.

How? There is a small tube that connects the corner of the eye to the area behind the nose. It’s called the tear duct and this tube is the reason why your nose starts running when you ugly cry.

If your child’s nose is bleeding a lot or if they are trying to stop a bloody nose by applying pressure and sneeze or blow out hard, the blood can come out the duct as a tear.

What do you do for your child if they have bloody tears? Of course, it’s different for each cause. If there’s a stick coming out of it, go to the emergency room. If the child has had red eyes, other signs of easy bleeding or you can find no other cause, call your doctor. If your child has had a bloody nose, continue to apply pressure to the nose to stop the bleeding. Once the bloody nose has stopped, the bleeding tears should stop. If it doesn’t, call your doctor.
