Understanding Low Growth Rates
My son, who is 8 and a half years old, stands at only 46 inches and weighs just about 50 pounds. He has unfortunately fallen off the growth chart. He was born weighing 8 pounds 6 ounces and measuring 21 inches, yet his growth has consistently lagged behind that of his siblings. His older sister, younger sister, and baby brother are all developing at a typical pace. When we first consulted our pediatrician, they suggested that his slower growth might be attributed to my Asian heritage and my height of 5'2”, along with my father's similar stature. However, my family has a mix of average and taller members, and my husband is 5'11”, which casts doubt on that explanation. My other children are growing without any issues, so I remain unconvinced by this reasoning. Last year, he underwent an endoscopy to check for potential nutrient malabsorption, and the results were normal. Recently, his bone age assessment also indicated that he is normal in that regard. Aside from being diagnosed with Autism and ADHD, there don’t seem to be any physical abnormalities that could explain this slow growth. Is there a possibility of any underlying rare conditions contributing to his unusually slow height increase? While he and his siblings, except for the baby, all tend to be fussy eaters, he is the only one who has not been growing. Currently, his pediatrician is taking a wait-and-see approach, but my patience is running thin. It’s noteworthy to mention that my 11.5-year-old daughter has grown two inches in the same time my son hasn't budged. I'm looking for suggestions to discuss with the pediatrician during our next appointment. Are there specific tests I should ask about? I am even considering the possibility of discussing growth hormone injections at this point.

It's understandable to be concerned about your son's growth, especially when compared to his siblings. Given that he has been assessed by a pediatrician and undergone tests, it’s wise to explore your concerns and seek further clarity. While differences in growth can often be attributed to familial patterns, underlying issues can sometimes be overlooked. Here’s a structured approach for you to consider for your next pediatric appointment.
Key Points:
- Growth Patterns: Your son's height is significantly lower than expected, especially given the normal growth of his siblings.
- Initial Assessments: Previous checks (endoscopy and bone age assessment) returned normal results, providing some reassurance.
- Consideration for Underlying Conditions: Despite normal assessments, persistent concerns warrant deeper investigation.
Explanation:
Children can experience variations in growth due to a number of reasons, including genetics, nutrition, hormonal factors, and other health conditions. Since your son has been diagnosed with Autism and ADHD and is a fussy eater, nutritional intake may play a role even if initial assessments are normal. Additionally, while familial height patterns are a possibility, they do not solely define growth, especially in the context of other siblings growing normally.
Next Steps:
-
Prepare for the Pediatric Appointment:
- Write down all concerns and recent observations, especially changes in eating habits and energy levels. Track any patterns you notice over time.
-
Discuss Specific Tests:
- Thyroid Function Tests: Ask for a full thyroid panel to rule out thyroid dysfunction, which can affect growth.
- Growth Hormone Levels: Discuss the possibility of checking levels of growth hormone, especially if you suspect the need for growth hormone therapy.
- Nutritional Assessment: Consider eating habits and ask for a referral to a nutritionist if your son is not consuming a balanced diet. Assess micronutrient deficiencies, particularly vitamin D and iron.
-
Consider Referral to a Specialist:
- If concerns remain after discussing the above, ask for a referral to a pediatric endocrinologist who specializes in growth disorders. They may be able to conduct more specialized tests or provide further insights.
-
Monitor & Document:
- Continue to monitor his growth and any associated behaviors, including appetite changes or digestion issues. Document these details to share with your pediatrician or specialists.
-
Open Dialogue:
- Maintain a dialogue with your pediatrician about your concerns regarding the “wait-and-see” approach. You might express your desire for a more proactive evaluation, especially given the growth of his siblings.
Your anxiety is valid, and proactive engagement with your healthcare provider is crucial. It’s essential to advocate for your son’s health and ensure that his needs are being thoroughly assessed. Let me know if you have any more questions or need further information!

Seeking Insights: My Journey with Undiagnosed Neurological Symptoms
Hello everyone, I'm a 34-year-old female grappling with neurological symptoms that first appeared in October, and I’m eager to hear from anyone who might have faced similar challenges. My journey began with unexpected migraines, blurred vision, and an ongoing sensation of being off-balance or intoxicated. Gradually, I began experiencing mainly sensory-related symptoms, such as tingling and burning sensations, feelings of extreme heat and cold, sharp pains radiating in my arms and back, as well as discomfort in my hands and toes, alongside intermittent numbness. I also endure varying degrees of weakness and heaviness in my right side, specifically my arm and leg, although I haven’t suffered complete functional loss. The nature of my symptoms is erratic; they fluctuate rather than consistently deteriorate. An MRI revealed mild, scattered lesions in the white matter, which were deemed nonspecific. Further tests from a lumbar puncture returned normal results, showing no markers of inflammation, and the oligoclonal bands were not present. A thorough range of lab tests yielded no significant findings. After evaluating my case, the neurology team suggested a possible diagnosis of MS and administered a three-day course of intravenous steroids. While I noticed a slight improvement in some sensory pain, my symptoms persist and continue to vary day by day. I still experience headaches and pressure in my head along with episodes of blurred vision, but there have been no new deficits since treatment. I am reaching out to connect with others who have had similar experiences. I would like to learn about the insights or diagnoses you encountered and what treatments proved beneficial (such as those related to migraine disorders, dysautonomia, or sensory neuropathy, for example). If you have navigated a similar path, I would greatly appreciate your sharing your story. Thank you!
Should I Seek Medical Attention for Left Ear Pulsatile Tinnitus?
A 31-year-old woman reports an ongoing issue with pulsatile tinnitus, which she is currently experiencing solely in her left ear. Although she's noticed this condition intermittently before, she hadn’t paid it much mind due to the absence of pain. Recently, however, her curiosity piqued her interest in researching the condition, where she stumbled upon information suggesting it could be serious. Usually, she avoids searching online for health worries, but now she is contemplating whether a visit to the doctor might be warranted. Can anyone advise on the need for a medical evaluation in this case?
Concerns About Angular Cheilitis
I’m a 23-year-old woman with no history of smoking, and I’m seeking assistance regarding a health issue. Back in January, I experienced angular cheilitis three times, each episode involving a minor crack at the corner of my mouth that healed within a few days. Following the last occurrence, I became quite anxious due to saliva accumulation in that area. I found myself frequently brushing my finger along that spot. After a few days, I observed a small area forming that appeared white and had a rough texture. Eventually, I realized it was not just a coincidence, and I started taking action, but only after it became noticeably larger. To address it, I cleaned the area with a mix of alcohol and apple cider vinegar. I’m uncertain about what this issue could be, but I’ve recently begun using over-the-counter Clotrimazole cream while also keeping the area moisturized with either lanolin or petroleum jelly. Unfortunately, I haven’t noticed any improvement, and I’m concerned as it seems to be expanding. The patch continues to be rough and excessively dry. Although I can open my mouth wide without any cracks forming, I do feel tension in the skin, similar to having a bandage over that location. At times, I experience a burning sensation after thorough washing, and I’ve noticed tiny red spots appearing on the outer edges of the patch sporadically.
Unusual Heart Sensation
I’m an 18-year-old, weighing 50 kilograms and standing at 170 centimeters (and yes, I’m aware that I’m quite slender). For the past couple of years, I’ve developed a habit of smoking about half a pack of cigarettes each day. So, the other day I was lying on my left side, relaxing, when I stumbled upon an unusual sensation. It felt as though my heart was pulsating so intensely that it was almost outside my body. Out of curiosity, I pressed a bit on the area and was instantly hit with a rush; my head started to tingle, my vision momentarily blurred, and it felt as though my heart dropped. It was as if my entire system had malfunctioned. Just for context, I’ve experienced something similar before after a ketamine overdose, and it persisted for about a month afterward, occurring occasionally while trying to sleep or during random moments in bed. This current episode has me quite anxious, especially since it hasn’t happened in a while, but this time felt particularly alarming.
Experiencing Heart Palpitations Following Chest Impact
I'm a 17-year-old female who has struggled with tachycardia for several years, having been diagnosed with postural tachycardia syndrome (POTS) about five years ago, although I haven't pursued further testing because I haven't completely lost consciousness. Recently, over the past month or two, I've started to experience sensations of my heart skipping beats, accompanied by difficulty in breathing during these episodes. These occurrences have become significantly more frequent, even when I'm at rest. Five years ago, I underwent a Holter monitor test, which indicated primarily tachycardia with occasional premature ventricular contractions (PVCs), but nothing alarming was found. In early December, I was struck hard in the chest by an elbow while in a mosh pit, which resulted in some pain when taking deep breaths for a few days. My sternum became bruised and slightly swollen, and it remained tender to touch for about two weeks, but this discomfort was manageable. I still feel some soreness when stretching, although it’s not severe. Additionally, I have diagnoses of Crohn’s disease and hypermobile Ehlers-Danlos syndrome (HEDS), and I am currently on immunosuppressants. Given these circumstances, would it be advisable for me to seek medical evaluation, or could these symptoms be considered typical?
