Heatstroke is a condition caused by your body overheating, usually as a result of prolonged exposure to or physical exertion in high temperatures. This most serious form of heat injury, heatstroke, can occur if your body temperature rises to 104 F (40 C) or higher. The condition is most common in the summer months. Heatstroke requires emergency treatment. Untreated heatstroke can quickly damage your brain, heart, kidneys and muscles. The damage worsens the longer treatment is delayed, increasing your risk of serious complications or death. Grace ER is open 24/7 during the summer months to treat patients who get heat stroke. So what are the signs and symptoms?
SymptomsHeatstroke signs and symptoms include:
- High body temperature. A core body temperature of 104 F (40 C) or higher, obtained with a rectal thermometer, is the main sign of heatstroke.
- Altered mental state or behavior. Confusion, agitation, slurred speech, irritability, delirium, seizures and coma can all result from heatstroke.
- Alteration in sweating. In heatstroke brought on by hot weather, your skin will feel hot and dry to the touch. However, in heatstroke brought on by strenuous exercise, your skin may feel dry or slightly moist.
- Nausea and vomiting. You may feel sick to your stomach or vomit.
- Flushed skin. Your skin may turn red as your body temperature increases.
- Rapid breathing. Your breathing may become rapid and shallow.
- Racing heart rate. Your pulse may significantly increase because heat stress places a tremendous burden on your heart to help cool your body.
- Headache. Your head may throb.
When to see a doctorIf you think a person may be experiencing heatstroke, seek immediate medical help. Call 911 or your local emergency services number. Take immediate action to cool the overheated person while waiting for emergency treatment.
- Get the person into shade or indoors.
- Remove excess clothing.
- Cool the person with whatever means available — put in a cool tub of water or a cool shower, spray with a garden hose, sponge with cool water, fan while misting with cool water, or place ice packs or cold, wet towels on the person's head, neck, armpits and groin.
CausesHeatstroke can occur as a result of:
- Exposure to a hot environment. In a type of heatstroke, called nonexertional (classic) heatstroke, being in a hot environment leads to a rise in core body temperature. This type of heatstroke typically occurs after exposure to hot, humid weather, especially for prolonged periods. It occurs most often in older adults and in people with chronic illness.
- Strenuous activity. Exertional heatstroke is caused by an increase in core body temperature brought on by intense physical activity in hot weather. Anyone exercising or working in hot weather can get exertional heatstroke, but it's most likely to occur if you're not used to high temperatures.
- Wearing excess clothing that prevents sweat from evaporating easily and cooling your body
- Drinking alcohol, which can affect your body's ability to regulate your temperature
- Becoming dehydrated by not drinking enough water to replenish fluids lost through sweating
Risk factorsAnyone can develop heatstroke, but several factors increase your risk:
- Age. Your ability to cope with extreme heat depends on the strength of your central nervous system. In the very young, the central nervous system is not fully developed, and in adults over 65, the central nervous system begins to deteriorate, which makes your body less able to cope with changes in body temperature. Both age groups usually have difficulty remaining hydrated, which also increases risk.
- Exertion in hot weather. Military training and participating in sports, such as football or long-distance running events, in hot weather are among the situations that can lead to heatstroke.
- Sudden exposure to hot weather. You may be more susceptible to heat-related illness if you're exposed to a sudden increase in temperature, such as during an early-summer heat wave or travel to a hotter climate. Limit activity for at least several days to allow yourself to acclimate to the change. However, you may still have an increased risk of heatstroke until you've experienced several weeks of higher temperatures.
- A lack of air conditioning. Fans may make you feel better, but during sustained hot weather, air conditioning is the most effective way to cool down and lower humidity.
- Certain medications. Some medications affect your body's ability to stay hydrated and respond to heat. Be especially careful in hot weather if you take medications that narrow your blood vessels (vasoconstrictors), regulate your blood pressure by blocking adrenaline (beta blockers), rid your body of sodium and water (diuretics), or reduce psychiatric symptoms (antidepressants or antipsychotics). Stimulants for attention-deficit/hyperactivity disorder (ADHD) and illegal stimulants such as amphetamines and cocaine also make you more vulnerable to heatstroke.
- Certain health conditions. Certain chronic illnesses, such as heart or lung disease, might increase your risk of heatstroke. So can being obese, being sedentary and having a history of previous heatstroke.
ComplicationsHeatstroke can result in a number of complications, depending on how long the body temperature is high. Severe complications include:
- Vital organ damage. Without a quick response to lower body temperature, heatstroke can cause your brain or other vital organs to swell, possibly resulting in permanent damage.
- Death. Without prompt and adequate treatment, heatstroke can be fatal.
PreventionHeatstroke is predictable and preventable. Take these steps to prevent heatstroke during hot weather:
- Wear loosefitting, lightweight clothing. Wearing excess clothing or clothing that fits tightly won't allow your body to cool properly.
- Protect against sunburn. Sunburn affects your body's ability to cool itself, so protect yourself outdoors with a wide-brimmed hat and sunglasses and use a broad-spectrum sunscreen with an SPF of at least 15. Apply sunscreen generously, and reapply every two hours — or more often if you're swimming or sweating.
- Drink plenty of fluids. Staying hydrated will help your body sweat and maintain a normal body temperature.
- Take extra precautions with certain medications. Be on the lookout for heat-related problems if you take medications that can affect your body's ability to stay hydrated and dissipate heat.
- Never leave anyone in a parked car. This is a common cause of heat-related deaths in children. When parked in the sun, the temperature in your car can rise 20 degrees F (more than 6.7 C) in 10 minutes. It's not safe to leave a person in a parked car in warm or hot weather, even if the windows are cracked or the car is in shade. When your car is parked, keep it locked to prevent a child from getting inside.
- Take it easy during the hottest parts of the day. If you can't avoid strenuous activity in hot weather, drink fluids and rest frequently in a cool spot. Try to schedule exercise or physical labor for cooler parts of the day, such as early morning or evening.
- Get acclimated. Limit time spent working or exercising in heat until you're conditioned to it. People who are not used to hot weather are especially susceptible to heat-related illness. It can take several weeks for your body to adjust to hot weather.
- Be cautious if you're at increased risk. If you take medications or have a condition that increases your risk of heat-related problems, avoid the heat and act quickly if you notice symptoms of overheating. If you participate in a strenuous sporting event or activity in hot weather, make sure there are medical services available in case of a heat emergency.
Sometimes asthma symptoms are mild and go away on their own or after minimal treatment with asthma medicine. Other times, symptoms continue to get worse. When symptoms get more intense and/or more symptoms occur, you're having an asthma attack. Asthma attacks also are called flareups or exacerbations (eg-zas-er-BA-shuns). Treating symptoms when you first notice them is important. This will help prevent the symptoms from worsening and causing a severe asthma attack. Severe asthma attacks may require emergency care, and they can be fatal. Asthma (AZ-ma) is a chronic (long-term) lung disease that inflames and narrows the airways. Asthma causes recurring periods of wheezing (a whistling sound when you breathe), chest tightness, shortness of breath, and coughing. The coughing often occurs at night or early in the morning. Asthma affects people of all ages, but it most often starts during childhood. In the United States, more than 25 million people are known to have asthma. About 7 million of these people are children.
OverviewTo understand asthma, it helps to know how the airways work. The airways are tubes that carry air into and out of your lungs. People who have asthma have inflamed airways. The inflammation makes the airways swollen and very sensitive. The airways tend to react strongly to certain inhaled substances. When the airways react, the muscles around them tighten. This narrows the airways, causing less air to flow into the lungs. The swelling also can worsen, making the airways even narrower. Cells in the airways might make more mucus than usual. Mucus is a sticky, thick liquid that can further narrow the airways. This chain reaction can result in asthma symptoms. Symptoms can happen each time the airways are inflamed.

What Is Anemia?
What Causes Anemia ?
- Anemia caused by blood loss
- Anemia caused by decreased or faulty red blood cell production
- Anemia caused by destruction of red blood cells
To diagnose anemia, your doctor will likely ask you about your medical history, perform a physical exam, and order blood tests.
Blood tests will not only confirm the diagnosis of anemia, but also help point to the underlying condition. Tests might include:
Your doctor may not treat your anemia until the underlying cause has been established. The treatment for one type of anemia may be both inappropriate and dangerous for another type of anemia.
How Do I Know if I Have Anemia?
- Complete blood count (CBC), which determines the number, size, volume, and hemoglobin content of red blood cells
- Blood iron level and your serum ferritin level, the best indicators of your body's total iron stores
- Levels of vitamin B12 and folate, vitamins necessary for red blood cell production
- Special blood tests to detect rare causes of anemia, such as an immune attack on your red blood cells, red blood cell fragility, and defects of enzymes, hemoglobin, and clotting
- Reticulocyte count, bilirubin, and other blood and urine tests to determine how quickly your blood cells are being made or if you have a hemolytic anemia, where your red blood cells have a shortened life span
What Are the Treatments for Anemia?
1. Water helps prevent dry mouth.Water keeps your throat and lips moist and prevents your mouth from feeling dry. Dry mouth can cause bad breath and/or an unpleasant taste–and can even promote cavities.
2. Water promotes cardiovascular health.Dehydration lowers your blood volume, so your heart must work harder to pump the reduced amount of blood and get enough oxygen to your cells, which makes everyday activities like walking up stairs–as well as exercise–more difficult.
3. Water keeps your body cool.Your body releases heat by expanding blood vessels close to the skin’s surface (this is why your face gets red during exercise), resulting in more blood flow and more heat dissipated into the air. When you’re dehydrated, however, it takes a higher environmental temperature to trigger blood vessels to widen, so you stay hotter.
4. Water helps muscles and joints work better.When you’re well hydrated, the water inside and outside the cells of contracting muscles provides adequate nutrients and removes waste efficiently so you perform better. Water is also important for lubricating joints. Contrary to popular belief, muscle cramps do not appear to be related to dehydration, but, instead, to muscle fatigue, according to Sam Cheuvront, Ph.D., an exercise physiologist.
5. Water keeps skin supple.When a person is severely dehydrated, skin is less elastic. This is different than dry skin, which is usually the result of soap, hot water and exposure to dry air. And, no, unfortunately, drinking lots of water won’t prevent wrinkles.
6. Water helps cleanse your body — inside and out.Your kidneys need water to filter waste from the blood and excrete it in urine. Keeping hydrated may also help prevent urinary tract infections and kidney stones. If you are severely dehydrated, your kidneys may stop working, causing toxins to build up in your body.
What are Lice?
Head lice are tiny, wingless insects that live on the human scalp. They are about as big as sesame seeds. Head lice sustain themselves by sucking blood—just as mosquitoes do. However, unlike mosquitoes, lice cannot fly or jump from one person to another; they can only crawl. Children often get head lice from head-to-head contact with other children, but may also get them by sharing personal items such as hats, combs, or headbands
What are lice, eggs (nits)?Lice eggs are laid by the female louse. They are about the size of a poppy seed and are difficult to see because their color blends in easily with hair. Lice eggs are laid near the root of the hair and are attached to the hair shaft with a glue-like substance that can't be washed or blown away. Nits are the empty eggshells left behind when lice hatch from eggs. Dandruff, sand and flakes of hairspray are commonly mistaken for lice eggs or nits. Eggs and nits are not easily removed and must be carefully combed out with a fine-tooth comb. Eggs and nits vary in color, from yellowish-brown to white. Since the hair grows, nits are usually found further away from the root of the hair. Many schools have a "No Nit Policy," which means children who have had head lice are not readmitted to school until all the nits are gone. If you have seen live lice on your child's head, it is very important to comb out eggs and nits as part of the lice treatment process. Lice treatment products should not be used if lice or nits have not been seen
How long do head lice live?Head lice live for approximately 40–50 days and go through 3 stages in their life cycle:
Egg Stage: The female louse lays the egg with a special glue that cements it to the hair shaft near the root. The lice egg develops and hatches approximately 10 days later. Nymph Stage: Once the louse hatches, it is called a nymph and is barely visible to the naked eye. The nymph cannot reproduce because it is not fully developed. After about 12 days, it becomes an adult. Adult Stage: The female adult louse can lay up to 10 eggs per a day—starting another generation of lice. The adult stage lasts about 30 days. Lice do not live longer than 2 days if they are separated from the head.
Learning that someone in your family has lice is never welcome news. But there's no need to feel overwhelmed by the prospect of getting rid of lice or preventing them from coming back. With the right information about what kills them, and the right tools, you will be better prepared to get RID® of them.
In pregnancy, some types of bleeding are a big issue, while others are not. Subchorionic bleeding is just one type of bleeding. Some cases can become serious, while others don’t adversely affect the pregnancy. But it’s important to call your doctor right away when you experience any form of vaginal bleeding. Subchorionic bleeding occurs when the placenta detaches from the original site of implantation. This is called a subchorionic hemorrhage or hematoma. It affects the chorionic membranes. These membranes lift apart and form another sac between the placenta and the uterus. The movement and resulting clots are what cause this type of bleeding. These hematomas can range in size, with the smallest being most common. Larger versions can cause heavier bleeding. Bleeding that goes beyond a few spots and requires a panty liner is often a sign of something else. Subchorionic bleeding is one such possibility. Bleeding tends to be the only sign or symptom of subchorionic hematoma. You may not even realize you have one until your doctor performs an ultrasound. If a diagnosis of vaginal bleeding is deemed subchorionic, then your doctor will likely start treatments to prevent miscarriage. Options may include progesterone or dydrogesterone. If the hematomas are large, you may also be ordered to:
- stay in bed (bed rest)
- avoid standing for long periods of time
- avoid sex
- avoid exercise
Allergy season is currently at its peak in Houston. Grace ER can help you treat and manage your symptoms. While there is still no cure for allergies (or hay fever), there are ways to diminish allergy symptoms. There are three types of treatments that can be used in combination:
- AVOIDANCE of the allergen,
- MEDICATION (anti-histamines),
- IMMUNOTHERAPY (allergy shots).
You’ve probably heard people talking about the stomach bug or stomach flu going around at work or your child’s school. But what exactly is it? The technical term for this sickness is viral gastroenteritis, which is an inflammation of the stomach and intestines. Food poisoning is different. It’s more common than the stomach bug. About 1 in 6 Americans, or roughly 48 million people, experience food poisoning each year.Source: https://www.healthline.com/
What are the symptoms?
Symptoms of a stomach bugIf you have the stomach bug, or viral gastroenteritis, you may have one or more of the following symptoms:
- stomach cramps
- a fever
- weight loss
- joint aches
- muscle aches
Symptoms of food poisoningTypical symptoms of food poisoning include:
- stomach cramping
- diarrhea or constipation
- a fever
- muscle aches
- general malaise
- bloody stool or vomit
- severe abdominal cramping
- a loss of consciousness
Fear and anxiety are part of life. You may feel anxious before you take a test or walk down a dark street. This kind of anxiety is useful - it can make you more alert or careful. It usually ends soon after you are out of the situation that caused it. But for millions of people in the United States, the anxiety does not go away, and gets worse over time. They may have chest pains or nightmares. They may even be afraid to leave home. These people have anxiety disorders. Types include
- Panic disorder
- Obsessive-compulsive disorder
- Post-traumatic stress disorder
- Generalized anxiety disorder
