Patient's Query

Hi doctor,

Is it possible to dehydrate yourself overnight? For about 11 months, I was malnourished and dehydrated. I have been drinking water, eating well, and gaining weight since then. All of this has been going on for over a year. I consume electrolyte-enhanced water. I recently had a blood test to check my electrolytes, and the results were normal. I drink at least 60 ounces of water daily, plus juice and tea. I drank 68 ounces of water, a cup of chai tea, and about 8 ounces of juice yesterday. Last night was scorching. I woke up in the middle of the night and fell back asleep. My body gets hot quickly, and I occasionally have night sweats (not sure of the cause of night sweats, but possibly a side effect of my medication).

I felt terrible when I woke up this morning. My head did not feel right (it is difficult to describe how it felt), and my body felt weak and as if I had gotten out of a sauna. I drank water immediately and felt better about an hour and a half after waking up and drinking 15 ounces of water. Is it possible that I was dehydrated? I am concerned that I was dehydrated at night, despite being told several times that you cannot get dehydrated overnight. Also, what can I do to avoid getting dehydrated overnight if you believe I am? I drink water throughout the day, including before going to bed. I do not know what else I can do. What could it be if you do not believe it is dehydration or something else?


Welcome to icliniq.com.

I understand your concern.

I believe it is due to dehydration or psychological stress, as you previously overcame malnourishment and dehydration. On the other hand, it could be a reflex reaction. Do not panic. Instead, drink four liters of water and eat a balanced diet. It is a mild anxiety symptom because you think and are connected to the past. Please do not sacrifice your eating habits. Eat healthily, and be wise.

I would like to know the cause of malnutrition back then. Was it because of bulimia or a chronic illness? That history will be helpful in assisting you further. But for the time being, my advice is to relax and not think about past diseases. Do not drink water at night because it will disrupt your sleep and cause further sleep deprivation and stress. Instead, drink 16 cups of water by 7 P.M.

Patient's Query

Hi doctor,

Thank you for the reply.

Postpartum depression and anxiety were the root causes of my dehydration and malnutrition. I never had these mental illnesses before giving birth to my child. However, I was very ill after having her, had no appetite, was in bed all the time, depressed, dizzy, nauseous, and dehydrated. It continued for 11 months. I was underweight. I consulted a doctor and started antidepressants immediately, and I have been on medication, hydrated, and eating healthy. I put on weight. My health has improved, but not nearly as much as it used to be.

I have orthostatic hypotension (not sure what the cause is or why it continues even though I drink a lot of water), I wake up feeling cranky some days, and my body does not feel right. I also get brain fog and feel lethargic. It almost feels like I am drunk or that I just ran on a treadmill and got off, leaving me with that strange feeling in my head.

It is difficult to describe, but it occurs to me frequently. My body is weak, resulting in poor posture. In addition, most of the weight was around my belly, making me bloated, which made me feel very uncomfortable and affected my posture. My heart rate is always increasing. I take multivitamins and Vitamin D supplements. I recently had a blood test to check my thyroid hormones, vitamins, electrolytes, iron, and so on, and everything was normal.

As you can see, this traumatic experience has left me with a slew of symptoms. How can I recover from this situation? And also I would like to know why it occurs.


Welcome back to icliniq.com.

I understand your concern.

Proper treatment can completely cure postpartum psychosis. Women recover from postpartum psychosis within a few weeks of treatment, but full recovery can take much longer. So, the symptoms you described are the most common side effects of antidepressants, such as insomnia, anxiety, restlessness, dizziness, tremors, sweating, sleepiness, fatigue, dry mouth, diarrhea, constipation, and headaches.

It would be best if you were not concerned. Once you stop taking the medication or your doctor reduces the dosage, these symptoms will fade. I am glad you are on the right track and taking medications. However, remember to take your antidepressant precisely as prescribed by your doctor. Also, your consumption of water and eating a healthy diet are excellent. Adding a few daily activities, such as socializing with people, meditating, and maintaining a happy environment, will help you recover fast. I assure you that you will feel better soon. Do not worry about the side effects of your medications. Discuss them with your doctor.

Same symptoms don't mean you have the same problem. Consult a doctor now!
