3 Myths About Dehydration that Could Hurt You

Summertime can be the busiest time of the year. Not only are you getting all your projects done, but you’re also squeezing in all the fun you can. This extra running, combined with our excessive Texas heat, can result in dehydration if you’re not careful with your water intake. Left unchecked, dehydration can quickly become serious.
Dehydration Explained
Dehydration is the lack of sufficient water for your body’s needs. Symptoms can begin with even as little as 1.5% fluid loss.1
When the body is low on water, several adverse things begin to happen.
- Your heart must work harder to pump blood2
- Your muscles don’t move efficiently
- Your feet and hands may swell as your body retains fluid
- You start to feel really sick: dizzy, headache, dry mouth, pounding heart, shaky
Dehydration can be caused by not getting enough water and by exercising, drinking alcohol, taking certain medications, unrelenting hot weather, or by being sick with vomiting or diarrhea.
But many of us are used to living with a certain level of dehydration and we tell ourselves it will be ok because we’ve pushed the envelope before. Here are 3 common myths that need to be debunked when it comes to protecting yourself from the adverse effects of dehydration.
Myth #1 – Drink when you’re thirsty and you’ll be fine
“Waiting to drink water when you are thirsty is not the best plan of action against dehydration,” said Medco ER’s Medical Director, Dr. Nasir Khan. “Your body will already be struggling to get back to a comfortable hydration point, especially if countering the effects of hot weather or exercise. Also, as you age, your thirst indicator becomes less noticeable and, thus, less reliable.”
Pro Tip: Drink before you notice thirst and keep up the water intake throughout the day.
Myth #2 – Drinking a lot of water quickly will take care of it
Drinking excessive amounts of water at one time is not the best way to remain hydrated all day. Your body will rapidly purge more and retain less, leaving you still dehydrated as you keep working or the heat remains an issue.
Pro Tip: Drink small amounts of water throughout the day to make sure you are getting plenty.
Myth #3 – Dehydration is unpleasant but not dangerous
“Dehydration can quickly become dangerous and even deadly,” said Dr. Khan. “We treat patients all the time with IVs and electrolyte intervention to try to restore them to health. It’s not something to take lightly.”
Additionally, it can contribute to an imbalance of electrolytes—or hypernatremia—which can make you very sick. Another complication that is made worse by dehydration is low fluid levels in the cells of the body, or hypovolemia. Over time, liver and kidney damage can occur. Most of these complications can be alleviated with proper hydration habits.
Pro Tip: Help educate those around you and establish good hydration habits in their lives.

Are Energy Drinks Really Bad for You?

A late morning or an early afternoon slump may have you reaching for an energy drink to boost your energy and power up for the rest of the day. Packaged in attractive and portable cans, these drinks seem like little more than a soda designed to give you wings. But regular consumption can actually result in a quick trip to the emergency room or a fast track to a chronic health condition like hypertension.1
Marketed to youth, energy drinks are consumed mostly by children, teen and young adults. “While the American Academy of Pediatrics warns that children and adolescents should not consume energy drinks, there still are many who do,” said Medco ER’s Medical Director, Dr. Nasir Khan. “They seem mostly unaware of the risk they are taking in spiking their hormone levels, overdosing on caffeine, and gambling with exacerbating a latent condition they may not even know they have, such as a heart arrhythmia.”
What’s in an energy drink?
The main source of energy in an energy drink comes from caffeine. While caffeine content varies, energy drinks generally have three to six times the amount of caffeine as coffee does. Also, considering how quickly a can could be consumed, that could be comparable to drinking six cups of coffee in 30 minutes.
There are five basic components most energy drinks share.
- Caffeine – a legally addictive substance. Too much caffeine increases heart rate and blood pressure and causes insomnia and anxiety.2
- Taurine – an amino acid that possibly stimulates brain activity and increases physical performance.2 A ban on taurine has made many energy drinks illegal in other countries.
- Sugar – most people don’t realize that energy drinks contain as much or more sugar than regular sodas. That’s a whopping amount of sugar to consume regularly and can result in unhealthy weight gain.
- Guarana – from a tropical plant from South America, these seeds contain a high caffeine content.3
- Glucuronolactone – claimed to be a caffeine-like stimulant, there is no scientific evidence to support its use.3
What does your energy drink do to your body?
Caffeine triggers a supercharging of receptors which then release norepinephrine, dopamine and serotonin in the brain.1 Additionally, there is an increased risk of caffeine intoxication which causes a myriad of bad side effects and potentially lasting damage.
“Energy drinks can easily lead to caffeine overdoses which can lead to seizures, heart problems and death,” said Dr. Khan. “When combined with alcohol, the effects can be masked which can cause a person to not realize how much damage they are doing to their body.”
What are common symptoms of an energy drink-related emergency?
- Seizures
- Heart complications – irregular heartbeat, racing heart, heart failure
- Hypertension
- Hypotension
- Dehydration
- Anxiety
- Insomnia
How can I get an energy boost without the risk of energy drinks?
Eating a well-balanced diet rich in fruits and vegetables can help you get the vitamins and minerals needed to keep your energy at an even keel. Protein can give you long-lasting energy burns. Low-to-no caffeine teas or coffee can also be substituted for energy drinks. Sports drinks have a lot of additives but can be researched and considered as an alternative to energy drinks.
Getting plenty of water will help your body operate at its peak. Milk and 100% fruit juice should be offered in place of manufactured drinks.4 Sales of these drinks should take the place of energy drinks in schools and colleges.5

When IBS is an Emergency
Does this sound familiar: you’ve just finished a long, stressful day and had a good dinner and now the cramping begins. You spend the evening vacillating between trying to ignore the growing pain in your abdomen and trying to find relief in the bathroom. If this sounds like you, you may be suffering from irritable bowel syndrome (IBS).
“IBS is an often painful and recurring condition that could be masking a more serious condition. It could be caused by something like a bacterial infection or it could be caused by changes in the muscle contractions of the intestine,” said Medco ER’s Medical Director, Dr. Nasir Khan. “Some people find their IBS symptoms are triggered by stress and others find certain foods contribute to their discomfort.”
Symptoms of IBS
According to the NIH: National Institute of Diabetes and Digestive and Kidney Diseases, any or all of these symptoms may be present with Irritable Bowel Syndrome:1
- Abdominal pain
- Cramping
- Constipation
- Diarrhea
- Constipation and diarrhea
- Changes in bowel movements
- Bloating
- Gas
When IBS is an Emergency
If your abdominal pain or IBS is interrupting your life and the pain is so persistent that you can no longer function, go to the nearest emergency room. Your doctor will want to rule out other, more serious conditions.2
If you have a fever that accompanies abdominal pain or cramping, you should seek medical help.
Any unexplained and rapid weight loss needs to be discussed with your doctor.
If you have to get up in the night with diarrhea, that is something to discuss with your doctor.
When there are signs of any rectal bleeding or dark, tarry stools that indicate blood in the stool, you should go immediately to Medco ER.
If you have nausea and vomiting accompanying abdominal cramping, if you are dizzy or faint, if you have chest pain, or if you have difficulty breathing, go to the ER.
If your abdomen is painful to the touch or is hard and distended, go to Medco ER right away.
“Persistent abdominal pain that doesn’t lessen with trips to the bathroom can indicate a serious condition,” said Dr. Khan. “Come to Medco ER right away when you think something is wrong and let us take a look. We have full diagnostic capabilities at Medco ER, we have rapid results labs, and our doctors are board-certified and experienced in treating IBS.”
Treatment for IBS
If IBS is diagnosed and other, more serious conditions are ruled out, your doctor will have ideas to help you start to feel better. Since IBS is not a form of cancer and doesn’t damage the intestines, treatment usually begins with diet modifications. Your doctor may discuss a diet low in gluten and high in fiber.
Lifestyle changes, probiotics, exercise, sleep, and fluids could be recommended. Laxatives, fiber supplements, antidepressants, anti-diarrheal medications, and pain medications are some pharmaceuticals that your doctor may consider.2

While IBS may not seem like an emergency most of the time, when the pain interferes with your life, increases dramatically, or has accompanying symptoms like fever, nausea or chest pain, the team at Medco ER are ready to help you any time, day or night.

Top 10 Reasons to Go to the ER

Healthcare today gives you more choices than ever before. You can go to the doctor’s office, urgent care clinic, telehealth visit or emergency room. Even with all these choices, some choose to stay home and tough it out. But there are times when the emergency room is absolutely the right choice. The board-certified physicians at Medco ER in Plano, TX, have compiled ten reasons when going to the ER is your only option.
“If you’re wondering whether or not to go to the ER, ask yourself if it is not getting better over time, if pain has you sidelined, or if there is one of the warning signs of a serious condition,” said Medco ER’s Medical Director, Dr. Nasir Khan. “If you answer yes to any of those points, it’s best to come immediately and let us examine you.”
Blood Loss
Whenever the body is losing blood, a trip to the ER is the right thing to do. This could include any of the following:
- Coughing blood
- Vomiting blood
- Passing blood in the stool
- Excessive bleeding from a laceration
- Bleeding from a fracture
- Uncontrolled bloody nose
Fracture or Tear
If you have an injury and you’re not sure whether it is broken, fractured, torn or just bruised, your doctor at Medco ER can help. We can X-ray the area, apply a brace, or refer you to a specialist when needed.
Warning signs include: numbness or cold in the extremity that is injured, pain when moving the limb, bleeding accompanying the fracture, bone protruding, or misalignment of the limb. For any of these symptoms, go to Medco ER immediately.
Breathing Difficulties
If you or someone you love is struggling to breathe, pulling hard at each breath, making a wheezing sound with a breath, showing blueish discoloration around the mouth or fingertips, or has chest tightness, go to the nearest ER immediately. Whether it is a complication of COVID-19, an asthma attack, COPD or another cause, breathing difficulties must be addressed as an emergency.1
Chest Pain
Sudden or growing pain in the chest, jaw, neck, arm or back could indicate a heart problem that is an emergency. Other symptoms could include:2
- Tightness in chest
- Uncomfortable fullness feeling
- Heartburn
- Squeezing feeing in chest
- Pain in one or both arms
- Cold sweat
- Nausea
- Dizziness
- Shortness of breath
Stroke Symptoms
Symptoms of a stroke can come on suddenly and unexpectedly. If someone exhibits these symptoms, call 911 immediately.2 Every minute counts.
- Confusion or disorientation
- Arm weakness
- Partial paralysis or difficulty moving
- Unexplained drowsiness
- Difficulty speaking
- Change in vision
- Face drooping
Loss of Consciousness
Any time someone has lost consciousness, whether for a short time or is unresponsive, take them to the nearest ER or call 911. Loss of consciousness accompanied by seizures should also be seen by a physician immediately.
Head Injury
If you have fallen and hit your head, been hit in the head by an object, or had a severe shaking of the head, you might sustain a head injury or a concussion. Here are some warning signs3 that require a visit to the ER:
- Pain from the injury
- Confusion or disorientation
- Loss of consciousness
- Ringing of the ears
- Sudden drowsiness or fatigue
- Vision changes
- Nausea or vomiting
- Slurred speech
Burns
If you are suffering from a burn, consider the severity. Just going by pain level alone isn’t enough since minor burns often hurt worse than major burns.4 If it covers a large area, has penetrated deep, has discolored the skin, has swollen the area or has caused blisters, a trip to Medco ER is a good idea.
Abdominal Pain
Pain in the abdomen can indicate one of several conditions. All of them require immediate medical intervention. “If you’ve experienced abdominal pain for any length of time, it’s a good idea to come in and let us check you out,” said Dr. Khan. “It could be anything from a bleeding ulcer to gallbladder stones to a cyst. With a thorough examination and imaging scan, we should be able to diagnose the problem.”
Extreme Pain
If you’re experiencing extreme pain that isn’t responding to over-the-counter medication and isn’t getting better with time and rest, your body is trying to tell you something. It’s time to go to Medco ER.
- Migraine or headache
- Back pain
- Shooting pain
- Chest pain
- Pain when eating
- Pain that takes away your appetite
- Throbbing pain
- Eye pain
- Toothache
- Stomach pain

Is it COVID or is it Flu?

Today, if you wake up with a headache, fever, sore throat, cough and body aches, you probably will spend significant time wondering if it is the flu or COVID. In the past, you may have spent a few minutes running down a list of people you’d been around who had the flu, but now you have to worry about exposure to COVID-19. As the threat of the new Omicron variant looms large, we have to be especially vigilant with ourselves and our children. So how do you know if it’s Influenza A or if it’s COVID? At Medco ER & Urgent Care in Plano, TX, our board-certified physicians are here to help you answer that dilemma.
“The difficulty is in the shared symptoms,” said Medco ER & Urgent Care’s Medical Director, Dr. Nasir Khan. “Both influenza and COVID can present with fever, chills, muscle soreness, and cough. Some people experience diarrhea and vomiting with either condition. So, short of getting tested, it is hard to know whether it’s flu or COVID.”
Shared symptoms
There are many similarities between flu and COVID-19, though the severity can vary. People may experience very mild cases of either condition, or they can experience severe cases and even need hospitalization. Either flu or COVID can result in secondary infections, such as pneumonia, and require advanced treatment.
Here’s a list of the common symptoms1 that can occur in either condition:
- Fever
- Chills
- Headache
- Body aches
- Fatigue
- Cough
- Congestion
- Runny nose
- Sore throat
- Nausea
- Vomiting
Unique symptoms
“One of the most prominent symptoms that may help you know the difference is the classic loss of the senses of taste and smell. Usually, that is a good way to realize you probably have COVID and should come in and get tested right away,” said Dr. Khan. “Additionally, if you have difficulty breathing or shortness of breath, that is another indicator of COVID, but it could also mean you’re moving into a chest condition with the flu. But that should be looked at right away by one of our qualified physicians.”
How it is spread
Both the flu and COVID are highly contagious, though they are caused by completely different viruses. They are both spread through contact with other people who are infected with the germs. Coughs and sneezes can transmit microscopic droplets laden with the virus, or even just talking can transmit the virus. When these droplets are inhaled or enter through the eyes or mouth, the virus then spreads to that person.2
Medco ER & Urgent Care is ready to help
If you are unsure if you have the flu or COVID, come to Medco ER & Urgent Care right away for a Rapid Antigen Test with one swipe swab. Results are ready in 15 minutes, so you will know right away if you have the flu or COVID. Not ready to come in? Try a telehealth visit and get fast advice from one of our board-certified physicians.
