Symptoms of the flu in adults
- Early flu symptoms can extend below the head, throat, and chest. Some strains of the virus can cause diarrhea, nausea, stomach pain, or vomiting. Dehydration is a dangerous complication of diarrhea and vomiting. To avoid dehydration, drink water, sports drinks, unsweetened fruit juices, caffeine-free teas, or broth.

Heart failure — sometimes known as congestive heart failure — occurs when the heart muscle doesn't pump blood as well as it should. When this happens, blood often backs up and fluid can build up in the lungs, causing shortness of breath. Certain heart conditions, such as narrowed arteries in the heart (coronary artery disease) or high blood pressure, gradually leave the heart too weak or stiff to fill and pump blood properly. Proper treatment can improve the signs and symptoms of heart failure and may help some people live longer. Lifestyle changes — such as losing weight, exercising, reducing salt (sodium) in your diet and managing stress — can improve your quality of life. However, heart failure can be life-threatening. People with heart failure may have severe symptoms, and some may need a heart transplant or a ventricular assist device (VAD). One way to prevent heart failure is to prevent and control conditions that can cause it, such as coronary artery disease, high blood press...
Heart failure can be ongoing (chronic), or it may start suddenly (acute). Heart failure signs and symptoms may include: 1. Shortness of breath with activity or when lying down 2. Fatigue and weakness 3. Swelling in the legs, ankles and feet 4. Rapid or irregular heartbeat 5. Reduced ability to exercise 6. Persistent cough or wheezing with white or pink blood-tinged mucus 7. Swelling of the belly area (abdomen) 8. Very rapid weight gain from fluid buildup 9. Nausea and lack of appetite 10. Difficulty concentrating or decreased alertness 11. Chest pain if heart failure is caused by a heart attack
Heart failure often develops after other conditions have damaged or weakened the heart. However, heart failure can also occur if the heart becomes too stiff. In heart failure, the main pumping chambers of the heart (the ventricles) may become stiff and not fill properly between beats. In some people, the heart muscle may become damaged and weakened. The ventricles may stretch to the point that the heart can't pump enough blood through the body. Over time, the heart can no longer keep up with the typical demands placed on it to pump blood to the rest of the body. Your doctor can determine how well your heart is pumping by measuring how much blood is pumped out with each beat (ejection fraction). Ejection fraction is used to help classify heart failure and guide treatment. In a healthy heart, the ejection fraction is 50% or higher — meaning that more than half of the blood that fills the ventricle is pumped out with each beat. But heart failure can occur even with a normal ejection fr...
A single risk factor may be enough to cause heart failure, but a combination of factors also increases your risk. Risk factors for heart failure include: 1. Coronary artery disease.Narrowed arteries may limit your heart's supply of oxygen-rich blood, resulting in weakened heart muscle. 2. Heart attack.A heart attack is a form of coronary artery disease that occurs suddenly. Damage to your heart muscle from a heart attack may mean your heart can no longer pump as well as it should. 3. Heart valve disease.Having a heart valve that doesn't work properly raises the risk of heart failure. 4. High blood pressure.Your heart works harder than it has to if your blood pressure is high. 5. Irregular heartbeats.These abnormal rhythms, especially if they are very frequent and fast, can weaken the heart muscle and cause heart failure. 6. Congenital heart disease.Some people who develop heart failure were born with problems that affect the structure or function of their heart. 7. Diabetes.Having d...
Complications of heart failure depend on the severity of heart disease, your overall health and other factors such as your age. Possible complications can include: 1. Kidney damage or failure.Heart failure can reduce the blood flow to your kidneys, which can eventually cause kidney failure if left untreated. Kidney damage from heart failure can require dialysis for treatment. 2. Heart valve problems.The valves of the heart, which keep blood flowing in the right direction, may not work properly if your heart is enlarged or if the pressure in your heart is very high due to heart failure. 3. Heart rhythm problems.Heart rhythm problems may lead to or increase your risk of heart failure. 4. Liver damage.Heart failure can cause fluid buildup that puts too much pressure on the liver. This fluid backup can lead to scarring, which makes it more difficult for your liver to work properly.
The key to preventing heart failure is to reduce your risk factors. You can control or eliminate many of the risk factors for heart disease by making healthy lifestyle changes and by taking the medications prescribed by your doctor. Lifestyle changes you can make to help prevent heart failure include: 1. Not smoking 2. Controlling certain conditions, such as high blood pressure and diabetes 3. Staying physically active 4. Eating healthy foods 5. Maintaining a healthy weight 6. Reducing and managing stress

Hemolytic uremic syndrome (HUS) is a condition that can occur when the small blood vessels in your kidneys become damaged and inflamed. This damage can cause clots to form in the vessels. The clots clog the filtering system in the kidneys and lead to kidney failure, which could be life-threatening. Anyone can develop HUS, but it is most common in young children. In many cases, HUS is caused by infection with certain strains of Escherichia coli (E. coli) bacteria. The first symptom of this form of HUSis several days of diarrhea, which is often but not always bloody. HUS may also be caused by other infections, certain medications or conditions such as pregnancy, cancer or autoimmune disease. In some cases, HUS is the result of certain genetic mutations. These forms of HUSusually do not cause diarrhea. . HUSis a serious condition. But timely and appropriate treatment usually leads to a full recovery for most people, especially young children.
The signs and symptoms of HUS may vary, depending on the cause. Most cases of HUS are caused by infection with certain strains of E. coli bacteria, which first affect the digestive tract. The initial signs and symptoms of this form of HUSmay include: 1. Diarrhea, which is often bloody 2. Abdominal pain, cramping or bloating 3. Vomiting 4. Fever All forms of HUS— no matter the cause — damage the blood vessels. This damage causes red blood cells to break down (anemia), blood clots to form in the blood vessels and kidney damage. Signs and symptoms of these changes include: 1. Pale coloring, including loss of pink color in cheeks and inside the lower eyelids 2. Extreme fatigue 3. Shortness of breath 4. Easy bruising or unexplained bruises 5. Unusual bleeding, such as bleeding from the nose and mouth 6. Decreased urination or blood in the urine 7. Swelling (edema) of the legs, feet or ankles, and less often in the face, hands, feet or entire body 8. Confusion, seizures or stroke 9. High...
The most common cause of HUS— particularly in children under the age of 5 — is infection with certain strains of E. coli bacteria. E. coli refers to a group of bacteria normally found in the intestines of healthy humans and animals. Most of the hundreds of types of E. coli are normal and harmless. But some strains of E. coli cause diarrhea. Some of the E.coli strains that cause diarrhea also produce a toxin called Shiga toxin. These strains are called Shiga toxin-producing E. coli, or STEC. When you are infected with a strain of STEC, the Shiga toxin can enter your bloodstream and cause damage to your blood vessels, which may lead to HUS. But most people who are infected with E. coli, even the more dangerous strains, don't develop HUS. Other causes of HUScan include: 1. Other infections, such as infection with pneumococcal bacteria, human immunodeficiency virus (HIV) or influenza 2. The use of certain medications, especially some of the medications used to treat cancer and some of t...
The majority of HUScases are caused by infection with certain strains of E. coli bacteria. Exposure to E. coli can occur when you: 1. Eat contaminated meat or produce 2. Swim in pools or lakes contaminated with feces 3. Have close contact with an infected person, such as within a family or at a child care center. The risk of developing HUSis highest for: 1. Children 5 years of age or younger 2. Adults 65 years of age or older 3. People who have a weakened immune system 4. People with certain genetic changes that make them more susceptible to HUS
HUScan cause life-threatening complications, including: 1. Kidney failure, which can be sudden (acute) or develop over time (chronic) 2. High blood pressure 3. Stroke or seizures 4. Coma 5. Clotting problems, which can lead to bleeding 6. Heart problems 7. Digestive tract problems, such as problems with the intestines, gallbladder or pancreas
Meat or produce contaminated with E. coli won't necessarily look, feel or smell bad. To protect against E. coli infection and other foodborne illnesses: 1. Avoid unpasteurized milk, juice and cider. 2. Wash hands well before eating and after using the restroom and changing diapers. 3. Clean utensils and food surfaces often. 4. Cook meat to an internal temperature of at least 160 degrees Fahrenheit. 5. Defrost meat in the microwave or refrigerator. 6. Keep raw foods separate from ready-to-eat foods. Don't place cooked meat on plates previously contaminated by raw meat. 7. Store meat below produce in the refrigerator to reduce the risk of liquids such as blood dripping on produce. 8. Avoid unclean swimming areas. Don't swim if you have diarrhea.
