In one sentence, describe what the following article is about: Acute kidney failure is usually diagnosed in people who are already hospitalized. However, if you’re not in the hospital, have a common underlying cause of kidney failure, and experience symptoms, you’ll need to see a doctor immediately.  Common causes of acute kidney failure include injury, blood clots, urethral blockages, severe dehydration, drug overdose, alcohol abuse, and infection. Symptoms of kidney failure include urination changes (such as producing little or no urine), fatigue or sluggish movements, metallic taste in your mouth, pain between your ribs and hips, seizures, and swelling due to water retention, especially in your legs, ankles and feet. Your doctor will need to perform tests to diagnose the underlying cause. They’ll then clear a blockage or clot, administer antibiotics, or take other steps to treat the underlying condition. While treating the underlying cause, you’ll receive medication to help control your fluid levels and blood potassium. During and after treatment, you’ll need to eat more healthy carbohydrates, such as fruits and vegetables. You’ll also need to limit the amounts of protein, salt, and potassium in your diet.  High protein foods include red meat, poultry, and eggs. Instead of these, you’d need to eat more fruits, vegetables, and foods that are high in fiber, like brown rice, lentils, and raspberries.   You’ll also need to swap high potassium foods, such as bananas, oranges, and potatoes, for low potassium options, such as apples, cabbage, grapes, green beans, and strawberries.  Always read the label on prepackaged and processed foods to make sure you’re not eating things with high amounts of sodium. Some people who experience acute kidney failure require dialysis, which is a procedure that filters blood when your kidneys can’t function. It’s often only temporary, but cases of severe kidney damage might require long-term dialysis.
Summary: Get immediate help if you experience symptoms. Start treatment for the underlying cause. Make kidney-friendly dietary changes. Ask your doctor if you need dialysis.

In one sentence, describe what the following article is about: Consult with someone who is an expert in Taekwondo to get the right weights for your height, weight, and experience. Put on the ankle weights after you are dressed in the morning and wear them constantly throughout the day, even when driving, or working if you can.  If they become uncomfortable to the point you can't bear it anymore,  take them off for a few minutes then put them back on.  This will work out your leg muscles and make your legs stronger. Make sure you focus on accuracy of your kick before proceeding to improving speed.
Summary: Buy ankle weights from a sporting goods store or department store. Put on a thick pair of socks. Don't practice kicking with weights on; you'll risk serious knee injury if you do! While wearing the weights, practice different leg exercises, such as lateral leg raises, lunges, squats. Practice your kicks as per usual, but without weights! Watch to see that after a few weeks you'll be so much faster at kicking when not wearing your weights that you'll be able to wait on someone to start to kick you, and you'll be able to kick them first.

In one sentence, describe what the following article is about: Give them appropriate verbal and physical support. Be loving and let them cry on you if they want to.   First, make sure your friend is okay with physical contact! For example, you might say, “Is it okay if I give you a hug?” or “Is it all right if I hold you?”. Physical contact can be very comforting, but ask your friend if they are okay with hugging, cuddling, or any other type of touching before you do it. Contact can make people feel better, but if they don't want it, don't do it. Sometimes just sitting quietly, whether it is in prayer or meditation or not, can help calm people and provide some comfort. Doing something active and physical can help your friend release negative physical energy. This can help calm your friend down or distract them from the situation for a moment.   For example, take a brief walk, jog, go for a swim, or bike ride. Do yoga, tai chi, or some simple stretching. Sometimes, the only thing you can do is try to keep your friend from thinking about what is bothering them.   Offer, or just take them, to do something that they like. Go for ice cream or a movie. Get them involved in a project, for example, sorting clothes to donate or gardening. Find something humorous like a funny meme, video clip, etc. to try to lighten your friend’s mood a bit.
Summary:
Don't be afraid to console them. Pray or meditate. Release some physical energy. Distract your friend.
