Signs you might be a narcissist include persistent grandiosity, craving admiration, low empathy, and disproportionate anger or shame at criticism—especially when these patterns harm relationships, work, or daily life. Because narcissism exists on a spectrum, there are several factors to consider—see below for specific behaviors to watch for, the difference between grandiose and vulnerable types, self-reflection questions and a free screening to try, plus when to seek a professional evaluation and what treatments can help.

Testing for Crohn’s disease uses a stepwise approach: symptom and history review; blood tests (CBC, CRP/ESR); stool tests to rule out infection and detect inflammation (calprotectin/lactoferrin); the gold standard is colonoscopy with ileoscopy and biopsies, with imaging (MRE/CTE, ultrasound, capsule) to map extent and complications. No single test confirms it—clinicians integrate all results to distinguish Crohn’s from mimics; there are several factors to consider, so see the complete details below for what each test shows, when to seek urgent care, and how results guide your next steps.

Treat bites by washing with soap and water, using 1% hydrocortisone or oral antihistamines for itch, applying cold compresses or oatmeal baths, avoiding scratching, and covering broken skin; most heal without complications. Seek medical care for signs of infection, fever, severe allergic symptoms, or if bites worsen or don’t improve after 7–10 days, and prevent new bites by laundering on high heat, encasing the mattress, and considering professional extermination. There are several factors to consider—see below for medication options, prevention steps, and red flags that can change your next steps.

Yes—when chosen and used correctly, it can be safe for teens, but there are several factors to consider. Start small with body-safe, phthalate-free materials, use plenty of water-based lube, clean before and after, don’t share, and stop if it hurts; seek care for heavy bleeding, severe pain, fever, or persistent symptoms. For important details on materials, sizing, hygiene, emotional readiness, consent/legal issues, and specific red flags, see below.

Yes—when narcissistic traits form a persistent pattern causing impairment and meet DSM-5 criteria, it’s diagnosed as Narcissistic Personality Disorder, a medical mental health condition (affecting about 6% of people); everyday self-centered behavior alone is not. There are several factors to consider; see below for the specific diagnostic criteria, signs to watch for, treatment options, and next-step guidance (including when to seek professional help).

For most healthy adults, creatine isn’t bad when used as creatine monohydrate at recommended doses; decades of studies find it safe and effective, with benefits for strength and recovery and no kidney harm in healthy users. There are several factors to consider—mild water-weight gain or stomach upset can occur, and people with kidney or liver disease, diabetes, those who are pregnant, or anyone under 18 should be cautious and talk to a clinician. See dosing, hydration, product quality, and when to seek care in the complete guidance below.

Crohn’s disease itself is rarely directly fatal, and with modern treatments most people live full lives—but there are several factors to consider. Serious complications (like bowel perforation or obstruction, severe bleeding, sepsis, malnutrition, infections from immunosuppressive therapy, and associated liver disease or colorectal cancer) drive most risk, while early diagnosis, tight disease control, and regular surveillance reduce it; see the complete details below to understand what to watch for and which next steps to take.

Crohn’s has a strong genetic component: first-degree relatives face a 10–30× higher risk and identical twins show 30–50% concordance, but genes account for only about half the risk—environment, gut microbes, diet, and smoking also play major roles. Researchers have identified over 70 risk regions (e.g., NOD2, ATG16L1), but there’s no single “Crohn’s gene,” so routine genetic testing has limited predictive value. There are several factors and next steps to consider; see below for important details that could impact your care.

Generally yes—dildo use is considered safe in uncomplicated pregnancies, and gentle vaginal stimulation hasn’t been shown to cause miscarriage or preterm labor. Be gentle and hygienic (body-safe materials, clean toy, lube, avoid deep thrusting), and stop/seek care with pain, bleeding, fluid leakage, or strong contractions; avoid use and talk to your clinician if you have placenta or vasa previa, ruptured membranes, active infection, unexplained bleeding, or a history of preterm labor/cervical insufficiency. There are several factors to consider, including safety tips and trimester-specific advice—see below for the complete answer.

There are several factors to consider. Brief soreness from size, inadequate lubrication, or hitting the cervix often improves with rest and safer techniques (use body-safe materials, plenty of lube, go slow, and avoid force), but stop and seek care if you have sharp or worsening pelvic pain, heavy or persistent bleeding, fever/chills, unusual discharge, or urinary burning/blood; see the complete guidance below for specific red flags, step-by-step safe-use tips, and when to choose urgent vs. routine care.

Yes—rheumatoid arthritis is a chronic, systemic autoimmune disease in which the immune system attacks the joint lining (synovium), causing inflammation, pain, stiffness, and progressive joint damage if untreated. There are several factors to consider, including hallmark symptoms, autoantibody testing (RF, anti-CCP), imaging, treatment options, and the importance of early rheumatology care—see below for key details that could inform your next steps.

Rheumatoid arthritis has a significant genetic component—about 60% of overall risk is inherited (not from a single “RA gene”), with variants like HLA-DRB1 and PTPN22 involved—but genes don’t determine destiny. Environmental factors such as smoking (the strongest modifiable risk), gum disease, hormones, and weight interact with those genes, so having a close relative with RA roughly doubles risk, yet most relatives never develop it. There are several factors to consider, including early symptoms and risk-reduction steps; see below for the complete answer and guidance on next steps.

There is currently no permanent cure for rheumatoid arthritis, but many people can achieve long-term remission and maintain quality of life with early, treat-to-target care. Most require ongoing DMARDs (sometimes biologics or JAK inhibitors) plus lifestyle changes, and stopping therapy often triggers flares; experimental immune-reset approaches remain investigational. There are several factors to consider—see below for key details that could affect your next steps, including treatment choices, monitoring, and when to seek urgent care.

Diet changes won’t cure Crohn’s, but evidence-based strategies—like the Crohn’s Disease Exclusion Diet combined with partial enteral nutrition—plus ensuring adequate calories and protein can reduce flares, aid remission, and prevent malnutrition; reintroduce foods slowly and work with a gastroenterologist or IBD dietitian. Emphasize lean proteins, cooked low-fiber produce, refined grains, and healthy fats; limit processed and high-fat foods, emulsifiers, alcohol, and high-fiber items during flares, and use nutrition formulas if intake is low. There are several important factors to consider—see below for the phased CDED plan, exact nutrition targets, micronutrient guidance, specific foods to include/avoid, when to use enteral nutrition, and red flags that need medical care.

Yes—always tell your doctor if you use creatine: while generally safe for healthy adults, it can raise creatinine on labs (mimicking kidney issues), interact with meds like NSAIDs/diuretics, and may warrant kidney/liver monitoring or tailored dosing, especially with underlying conditions or in pregnancy, breastfeeding, or youth. There are several factors to consider, and key details to share (product, dose, duration, other meds, symptoms) could change your next steps—see below for what to discuss with your clinician and when to seek care.

Common misconceptions include that it’s just IBS, only affects the colon, can be cured by diet or supplements, is mainly caused by stress, or that surgery is a cure. In reality, Crohn’s is an immune‑mediated inflammatory disease that can affect any part of the GI tract, requires individualized medical therapy (with diet and stress management as adjuncts), and often recurs after surgery without maintenance treatment. There are important tests, treatment options, and warning signs that can change your next steps—see complete details below.

Common mistakes include believing diet can cure Crohn’s, that one plan (like the Specific Carbohydrate Diet) works for everyone, that all fiber or all processed foods must be avoided, and that supplements/probiotics aren’t needed. In reality, diet supports but doesn’t replace medications; tolerance is highly personal and phase-dependent (flare vs remission); quality and individual triggers matter more than blanket bans; and many people need labs and targeted supplementation. There are several factors to consider—see below for practical guidance, risks to avoid, and next steps to discuss with your gastroenterologist and dietitian.

Five common misconceptions about endometriosis: it isn’t “just bad cramps,” it doesn’t always cause infertility, pregnancy or menopause don’t cure it, hysterectomy isn’t the only option, and it can affect organs beyond the pelvis (bowel, bladder, even chest). There are several factors to consider—how symptom patterns guide diagnosis, fertility preservation options, evidence-based medical vs surgical choices, and red flags that need urgent care—see the complete answer below to choose the right next steps for you.

The top myths include thinking RA is just wear-and-tear, that it only affects hands/feet, that it’s always symmetrical, that morning stiffness is brief, and that it only occurs in older adults—RA is autoimmune, can involve many organs, may start unevenly, typically causes 30+ minutes of stiffness, and can occur at any age. These details change diagnosis and urgency; if you have persistent swelling/warmth, long morning stiffness, or systemic symptoms, seek medical evaluation—see the complete explanations and next-step guidance below.

The four stages of rheumatoid arthritis are: Stage I (early, synovitis without X-ray damage), Stage II (moderate, joint space narrowing and periarticular bone loss), Stage III (severe, erosions and deformities), and Stage IV (end-stage, ankylosis/collapse with major loss of function). There are several factors to consider—testing, medication choices (DMARDs/biologics), rehab and surgical options, and complication risks—see below for details that can guide your next steps.

Migraine symptoms can span four phases: prodrome (mood changes, yawning/neck stiffness, trouble concentrating), aura (flashing lights or blind spots, tingling/numbness, speech difficulty), headache (throbbing one- or two-sided pain worse with activity, sensitivity to light/sound, nausea/vomiting), and postdrome (fatigue, brain fog, muscle aches). There are important variations, triggers, and red-flag symptoms (like sudden severe neurological changes) that can affect your next steps—including when to seek urgent care—so see the complete details below.

Crohn’s disease commonly causes abdominal pain/cramping (often lower right), chronic diarrhea, urgent bowel movements, bloating/gas, blood or mucus in stool, fatigue, loss of appetite, weight loss, and low‑grade fever. It can also affect areas outside the gut—mouth sores, painful skin nodules, joint pain/swelling, eye inflammation, and liver/bile duct issues—and lead to complications like strictures, fistulas, abscesses, malnutrition, and growth delays in children. There are several factors to consider; see below for important red‑flag symptoms (severe abdominal pain, high fever, heavy bleeding, persistent vomiting, dehydration, or new painful swelling near the anus) and guidance on next steps.

There are several factors to consider: migraines stem from a brain-based cascade—cortical spreading depression, trigeminal nerve activation, and CGRP-driven inflammation—plus central sensitization that lowers your trigger threshold. They’re influenced by genetics, fluctuating estrogen and sleep/circadian changes, and are often set off by foods/alcohol, stress, sensory stimuli, weather shifts, dehydration, or intense exertion. For specifics that could guide your next steps—including personalized triggers, effective acute and preventive treatments, and red-flag symptoms—see the complete details below.

Crohn’s disease doesn’t have a single cause; it usually arises from a mix of genetic susceptibility and a dysregulated immune reaction to the gut microbiome, shaped by environmental exposures. Key contributors include family history and genes (e.g., NOD2), loss of immune tolerance with chronic inflammation, microbiome imbalance (fewer beneficial bacteria or invasive strains), and triggers like smoking, highly processed diets, NSAIDs, stress, and certain infections. There are several factors to consider that can influence testing, risk reduction, and treatment—see below for important details that could affect your next steps.

There isn’t one single cause—endometriosis likely develops from multiple mechanisms working together, including retrograde (backward) menstruation, cellular transformation of pelvic lining, embryonic remnants, and the spread of endometrial-like cells via stem cells, blood, or lymph. Who is affected is further shaped by genetic susceptibility, estrogen-driven growth with relative progesterone resistance, and immune dysfunction/inflammation, with risk higher in those with a family history, early menarche, heavy or frequent periods, and possibly certain toxin exposures. There are several factors to consider; see below for important nuances that could influence your evaluation, diagnosis, and treatment options.

Bed bug bites typically appear as small, red, very itchy bumps—often with a tiny central punctum and sometimes a red halo—showing up in clusters or straight lines (“breakfast, lunch, and dinner”) on exposed skin like the face, neck, arms, and legs. There are several factors to consider (reaction timing can be immediate or delayed, how to tell them from mosquito/flea bites, and when to seek medical care); see the complete details below to guide diagnosis, relief, and preventing further bites.

A migraine is a neurological attack causing moderate-to-severe, throbbing head pain—often one-sided, worsened by movement, and lasting hours to days—typically with nausea and sensitivity to light and sound (and sometimes smells); many also have warning phases (prodrome, aura) and a lingering “hangover.” There are several factors to consider—including common triggers, the full range of acute and preventive treatments, and red-flag symptoms that require urgent care. See below for complete details that can guide your next steps and when to seek medical attention.

Endometriosis often feels like severe, deep pelvic pain and cramping that can start days before bleeding and last beyond it, with sharp or radiating pains, pain during sex, bowel or bladder pain, heavy or irregular bleeding, fatigue, and sometimes trouble conceiving. There are several factors to consider—see below for how it differs from typical period pain, when to seek medical care, and the full range of treatment and self-care options that could affect your next steps.

A covert narcissist is someone with the core traits of narcissistic personality disorder—grandiosity, need for admiration, and low empathy—who expresses them in a quiet, self-effacing, or victim-tinged way (think passive-aggression, envy, and hypersensitivity to criticism) that can be just as harmful to relationships. There are several factors to consider, including key red flags, how it differs from overt narcissism, and next steps like screening, diagnosis, therapy, and boundary-setting—see details below.

A migraine is a common neurological disorder that affects about 12% of people—especially women—and causes recurrent, often one-sided, throbbing headaches lasting 4–72 hours, typically with light and sound sensitivity, nausea or vomiting, and sometimes a brief visual or sensory aura. There are several factors to consider—types (with or without aura, chronic), personal triggers, red-flag symptoms, and proven acute and preventive treatments—that can guide your next steps; see the complete details below.
