Causes of Sudden Fainting: Medical Insights
What causes sudden faint

Neurosurgeon
Answered on 14th Aug '24
Sometimes, people faint unexpectedly. This occurs when blood doesn't reach the brain sufficiently. It might be low blood pressure, or maybe the heart rate dropped suddenly. Rapid standing, dehydration, and low blood sugar often cause fainting. To avoid it, stand up slowly from seated positions. Also, drink plenty of fluids regularly. Eating frequent meals helps maintain stable blood sugar levels.

IAM 27 sever year old I have severe head ache didn't drink much water last day and was working bit late
Male | 27
It sounds like you might be experiencing a tension headache, which can occur from dehydration, lack of rest, or stress, especially after long hours of work. To alleviate discomfort, begin by drinking plenty of water and aim to take short breaks to relax. Try gentle stretches or a warm compress on your forehead. Ensure you're getting adequate sleep. If these measures do not improve your condition or if symptoms worsen, it would be wise to consult a neurologist to rule out any underlying issues.

im facing a problem in which my legs start to become hot for just of 5-10 seconds. Whats the reason behnid this?
Male | 27
Many people feel sudden warmth, called hot flashes. These happen frequently for women, but men can get them too. Hormonal changes or reactions cause hot flashes. Stress, caffeine, or alcohol may trigger them. Staying cool, avoiding spicy foods, and relaxing can help manage hot flashes. If they continues being problematic, speak to your doctor.

Have a pulsating headache on both sides of my head since a month
Female | 18
Steady throbbing in your head for a month straight is a real downer. That might mean tension headaches. Stress, no sleep, eyes straining too much - those things can cause them. Take breaks from computer screens. Relax your body and mind. Sleep enough hours each night. Pain relievers you can buy without a prescription might help. Drink lots of water, too. But if the headaches won't go away, you should visit a neurologist to get checked out properly.

Female | 20
Twitching can be attributed to a lot of different things such as stress, being overworked, or too much coffee. At other times, the cause may be the nerve ability of the body. Make sure you sleep, eat healthfully, and drink enough water. You may wish to tell your medical provider that you are sleeping badly for this issue to be listed on your consultation form and assessed appropriately.

Female | 17
Headaches are a normal thing people get sometimes. The reasons can be stress, not sleeping well, not having enough water, or too much screen time. Even food or your surroundings may cause them. Drink water, get rest, eat healthy foods, and take breaks from screens regularly. Severe or frequent headaches mean you should talk to a neurologist. They happens for different reasons. It could be because of stress, lack of sleep, not drinking enough water, or even looking at screens for too long.

Female | 33
Epilepsy can be challenging at this time. It’s worrying that you have a few seizures each year. It may be a good idea to see a neurologist. They can help work out whether it’s safe for you to get pregnant while controlling your fitness. You need to strike the right balance for yourself and your unborn child too.

I tend to jump to worse case scenario but I recently got diagnosed with vertigo caused by middle ear fluid and recently it’s came back since where I am the weather has gotten worse and my vision is kind of blurry sometimes and I have a hard time focusing on someone when they are talking how likely is it that this is being caused by a brain tumor and not the middle ear vertigo or am I just completely over thinking this
Female | 21
The blurry vision and the difficulty in focusing can be the vertigo that the ear fluid causes. It is common and it does not mean that you have a brain tumor. The ear fluid can mess up your balance and vision. Usually, it gets better on its own, but you might need medicine or special exercises if the problem keeps bothering you.

Female | 28
You are experiencing symptoms that may be related to several factors, such as stress, fatigue, or possible vision issues. The shakiness and dizziness you describe can be concerning but are often manageable. It’s great that you’ve already consulted an eye specialist. I recommend you continue monitoring your symptoms and ensure adequate rest, hydration, and nutrition. If these feelings persist or worsen, please see a neurologist for a thorough evaluation. They can provide tailored advice and determine if further tests are necessary.

Hello sir, I have a pain in my left side skul part ...it had so many years .but now thepain gets worst...more pain...that pain passes to the left sideof ear ,eye, throat, hand also ...and one more thing is...now left eye is getting pain and falls tears also...what is this symptoms
Female | 26
You could be undergoing a migraine experience. Migraines can bring about severe pain in the head which is usually unilateral. It can then spread from the eye, ear, throat, and sometimes even to tearing. Going through the menopause, you may have seasonal hormonal changes. Most people feel that climate change can trigger migraines. To try to avoid migraines, note what triggers to look for, practice some relaxation techniques, and get over-the-counter drugs used with guidance under the care of your doctor could be some good ideas.

Please help me I'm 38 years old I have pain all over my body I feel sick all the time I'm tried all the time and I have nights sweats for the last week
Male | 38
It seems like you may have some symptoms which could mean many things. Pain everywhere, feeling bad a lot, always being worn out, and sweating at night are all signs of different illnesses. A virus infection might be one cause but so could an immune system disorder or even just stress alone. You need to see a doctor so that they can find out what is going on with you exactly--and then give feedback that is helpful for treating whatever this turns out to be.

I feel tired all the time...I feel dizziness and headache in the evening.
Male | 30
Feeling persistently fatigued along with dizziness and headaches can result from various factors, including stress, dehydration, lack of sleep, or nutritional deficiencies. Prioritizing rest, staying hydrated, and maintaining a balanced diet can be beneficial. Regular physical activity may also help improve your energy levels. However, persistent symptoms warrant attention. It is important to consult a neurologist to explore underlying issues and receive tailored guidance.

Hy. More than one month ago during shower I have washed my anus and ( probabile also my colon). I have removed the shower head and i have put the nozzle into my ass...like 3 or 4 times. Like 10 minutes later started a flash stabbing pain in my left big toe. Next days better little bit after i have niumbness, flashing sometimes prickling and tingling in my legs and arms. In this moment I have burning in my all upper body. ( in my back and arms burn , hot.) I don't have fever! So probabile I have neuropathy ( polyneuropathy) symptoms. My question is the anal douching it could have been caused this symptoms ? Or it's caused by something else?? I am 28 years old. I don't have other sickness. Sorry for my english.
Male | 28
Dependent on the symptoms given, it’s unlikely that anal douching causes your neuropathy symptoms. Neuropathy mostly comes from related factors such as diabetes or nerve injury neuropathy. For a proper diagnosis and treatment plan, see a neurologist. Meanwhile, avoid inserting anything into your anus and focus on staying healthy generally.

Intracerebral hemorrhage is a potential health issue that can lead to symptoms such as serious headaches, confusion, and muscle weakness. Possible reasons include high blood pressure, trauma, and certain health conditions. The treatment for internal brain bleed is an emergency medical intervention. To take or swallow any medicine without consulting the doctor can be harmful and can aggravate the condition. One should immediately go to a neurologist to get medical attention.

Female | 24
You experience stuttering, where speaking smoothly feels difficult. Maybe you feel nervous or tired. For some people, stuttering improves on its own, especially children. However, therapies, and techniques exist to support fluent speech. Speech therapy is one option. It's crucial to discuss with a speech therapist or doctor to find the appropriate path for you.

Sudden headache followed by Unconsciousness. It happens frequently. MRI, CT SCAN, Report are normal. Deprived sleep EEG shows abnormalities that is sudden spike in waves.

But after starting treatment/medication she couldn't recognise any giddiness. She got Unconsciousness and freefall on ground resulting in injury in other parts of body.
Female | 40
The person is said to be having a focal seizure, which is a type of seizure. This can lead to sudden headaches, unconsciousness, and loss of control. The brain wave patterns that are incompatible with the EEG confirm this. Doctors can prescribe these medications to control the seizures and thereby avoid any injuries resulting from falls. It's paramount to follow up your treatment with a neurologist for a thorough diagnosis and the right therapy.

My son 21 years old. Struggling with migrains. Have now started to feel pressure in forehead and dizzy. Have just now taken paracetamol 1 gram. Is it ok to take migraine medication he got from doctor last time now already? He is really scared to wake up and get it like last time. It was really bad with vomiting.
Male | 21
Weakness and sensitivity to light, as well as vomiting, may be the result of migraines. He is on paracetamol which is great, but he can also take the migraine medication his doctor prescribed if it is the case, even though it is soon after the paracetamol. It is important that the doctor’s guidance is adhered to and the medication is taken as instructed which will also help to prevent the next similar episode from happening.
